We are aware of an issue that affected multiple CityFibre circuits in Peterborough overnight that caused a total loss of service between the hours of 01:00 – 08:00 for some customers .
CityFibre are aware of the issue and have provided the below updates. At this stage all service should be restored.
06:12
CityFibre are currently working on a Change in Peterborough (PB1244) to upgrade some router firmware to resolve bugs which have been identified on some existing firmware, the Change window was due to finish at 06:00 14/06/2023. CityFibre have lost remote access to the router on site resulting in On Net and Off Net customer being down, FLM are on onsite pending access from BT as remote access to the site has also failed to allow the engineer to entre.
Once BT attend with override key to provide access. ETA 06:30, the FLM engineer he will attempt to connect to the router physically to restore service or reboot the device if necessary.
07:41
Following a reboot of router PB1244-RTR-1 with the support of the FLM engineer onsite service was restored at 07:15
If customers continue to experience further issues, please re-boot equipment. If issues persist following any re-boot please contact the CityFibre Service Desk to report.
At this time we believe all services restored. If your service was affected and has not been restored as of yet please reboot your CityFibre ONT and any related CPE in the first instance. If issues still persist please contact our Support Team via usual channels.
19:00
CityFibre have provided a further update on this issue and believe this issue now resolved following works yesterday and a period of monitoring:
Resolution Notes: Network Cards at two network locations replaced. The remaining two costed out links are internal to CityFibre and there is no impact to customers and will be forward managed separately
Resolved: 14:31 (Customer impact resolved post card Swap out at 19:25 on Saturday 23rd July).
We are also still seeing stability on affected circuits. As such we believe this issue now resolved.
If your service was affected and has not been restored as of yet please reboot your CityFibre ONT and any related CPE in the first instance. If issues still persist please contact our Support Team via usual channels.
16:00
CityFibre have provided a further update on this issue, please see below:
With errors continuing following the suspected faulty line card being replaced, focus has switched to another core device which connects directly to it. Joint investigations between CityFibre and the vendor of the other core device commenced a short while ago, and further alarms were quickly identified here.
The card causing the alarms was taken out of service in order for redundant links on another card to be forced into use. This will mitigate any remaining impact to services previously utilising that card and to prevent any further service disruption by our planned restoration activity.
The next stage is for engineers to attend the relevant location with replacement parts. The ETA for this activity is 18:30.
There is currently no customer service impact that we are aware of, with services either taking alternative routes round the network or utilising their designed service resiliency at this location.
We will provide a further update when we know more.
08:25
CityFibre have continued to work on this issue overnight, including sourcing replacement parts so they can swap out the affected card and arranging engineer resource to collect the parts and then attend site.
Currently ETA for Engineer to arrive at Slough DC is 08:30 this morning.
We will provide a further update when we know more.
21:00
CityFibre have provided a further update, please see below:
Engineering attendance has been requested to CityFibre Slough Datacentre to carry out a reseat of the card.
Once reseated they will remain on site for at least 30 mins to confirm success. If the issue manifests again then engineer will proceed with a Card Swap out.
Currently awaiting an ETA for engineers attendance to Slough.
We will provide a further update when we know more.
18:00
CityFibre have provided a further update, please see below:
Following discussions between CityFibre NOC and our hardware supplier, there have been developments on this incident in regards to restoration.
It has been found that the origin point of the issue is on a line card situated within a core network device. During these investigations, two major actions have taken place in an attempt to restore service. The first action was to perform a soft clear on the line card itself which appeared to restore service for a short period before the issue resurfaced. And the second action was performing a full remote reboot of the affected line card.
During a period of monitoring, it has been seen that an issue has surfaced following the full reboot which is currently being investigated on a conference call between CityFibre NOC and our hardware supplier. Following on from the results of these investigations, the next course of action would be for engineers to be engaged to attend the site of the affected line card in order to perform a physical reseat of the line card itself.
Further to this, we are also considering a line card replacement should the issue resurface following a short monitoring period after the line card reseat.
We will provide a further update when we know more.
15:45
CityFibre have provided a further update, please see below:
CityFibre NOC have been investigating further and have determined that the issue is emanating from a specific location with the core network. As such, this device has been checked and the hardware supplier has been contacted directly for a Priority 1 case to be raised with them. During this time, CityFibre NOC have attempted to alleviate some issues across the core network by performing a workaround to reroute traffic to avoid the suspected affected device.
All of the requisite logs have been provided and CityFibre NOC are working alongside the hardware supplier to determine our next course of action. As of yet, it is still unclear as to when full service can be restored however we will endeavour to provide this as soon as we have it available.
We apologise for the disruption and hope to have a further update soon.
We have had reports that some services have stabilised since the changes were made by CityFibre to reroute affected traffic.
We will provide a further update when we know more.
14:00
We are aware of an issue affecting multiple CityFibre circuits nationwide that is causing partial or complete loss of service.
CityFibre are aware of the issue and have confirmed it is Major Service Outage and that they are investigating the cause.
Issues first started to manifest around 11:45 on a few circuits and have progressed since then to affect more circuits.
Below is the latest update from CityFibre:
Completed Actions:
Current Action Plan: At this juncture, it has been determined that several tunnels are currently flapping following initial investigations by CityFibre NOC.
We are working to determine as to why the tunnels are flapping in order for restoration works to begin. At this point, we are unable to provide an estimated time of repair however once one is available we will provide it as soon as possible.
We apologise for the disruption and hope to have a further update soon.
We will provide a further update when we know more.
19:30
After investigating CityFibre have identified the drop some customers experienced on 19/07/2022 appears to have been down to a brief power issue at an Openreach Exchange were some CityFibre equipment for the area is located.
No further issues have been seen since that appear to be related and so is believed to be an isolated incident at this time. As such we consider this issue resolved.
12:25
We are aware of an issue that caused a drop in service on some CityFibre circuits in Peterborough between around 11:30 and 12:15 today.
We have raised this issue with CityFibre to advise what happened and will provide an update when we know more.
Services on the whole now appear to have recovered, but if you are still seeing a loss of service please reboot any relevant equipment in the first instance and if still not restored please get in touch through the usual channels.
17:00
Good Evening
Below is the latest update on this issue received 27/06/2022 PM from CityFibre. We have not shared this update before now due to some incidents that seemed possibly related that we have been waiting to receive clarity on before sharing this update and closing down the major incident ticket on our end.
We are now confidant the other incidents we observed are NOT related to this MSO with CityFibre but are in fact isolated incidents caused by separate issues/circumstances. Outside of these isolated incidents we have seen no evidence of reoccurrence this week.
As such we believe this issue now resolved.
Resolution Notes:
Following a 5 day period of extensive monitoring, no further impact has been experienced since approx. 12:00BST on the 22nd June 2022 when the MPLS path between Reading – Coventry was costed out of the network. CityFibre continued enhanced monitoring and engagement as we build confidence that our stability is restored.
Investigations into the root cause continue via City Fibre’s Problem Management process. CityFibre NOC and Network Engineer teams continue to liaise with Vendors Nokia and Ciena regarding root cause investigations.
Resolved: 22/06/22 12:00
If your service was affected and has not been restored as of yet please reboot your CityFibre ONT and any related CPE in the first instance. If issues still persist please contact our Support Team via usual channels.

Please see below the latest update provided by CityFibre on this issue:
CityFibre in conjunction with the vendor have completed their Technical conference call and have redefined the debug setup in the event of further LSP flaps. Following the meeting and recommendation from the vendor CityFibre have implemented additional captures across elements of our core network to capture more detail in the event of a reoccurrence. The technical session covered the detail below, however, at this juncture the underlying root cause has not been identified therefore we have no recovery plan.
• Reviewed the historical debug captures – no issues identified
• On vendor recommendation CityFibre have applied further debug captures on more nodes
• CityFibre network has been more stable today
• Amended the way the debugs are being stored to remove limitations
• Behaviours seen on another element of the network and an incident has been raised with Juniper. Feedback will flow into Nokia when we have the feedback.
At this juncture we have exhausted all avenues of investigation and CityFibre NOC continues to monitor the network for further LSP flaps. Nokia remain on point to support us from a technical perspective and review the analysis as we experience issues across the network.

12:00
Overnight CityFibre Changed the optics on the link between London and Cambridge – However we can see the network drops are still occurring.
The latest update from CityFibre is below:
We understand your frustration on this intermittent issue and please accept our apologies. The latest update is the following:
CityFibre has multiple teams working on this issue from the Network Operations Centre (NOC) and Architecture & Engineering.
CityFibre has a critical case open with Nokia.
One of the nodes in question is a core node in the CityFibre network within the London area and we cannot isolate or cost out traffic as the intermittent issues seems to be spread over multiple tunnels.
Rest assured this issue has the visibility within CityFibre and our vendor to drive resolution
We will update you further when we know more.
18:00
We have received an update from the supplier that a change is scheduled for 22:00 this evening on what is believe to be the affected link to address this issue.
As such we will be monitoring post this change for any further dropouts on our monitoring so we can make the supplier aware if we do see any.
We will update you further when we know more.
14:45
We have received a further update from the supplier on this issue:
CityFibre NOC continue to liaise with Nokia. Nokia continue focusing on node – lon5-1. The Debug output was provided to Nokia and we are currently awaiting their feedback.
Ciena is still engaging Tier 4 to investigate this issue.
We will update you further when we know more.
09:30
Works to resolve this issue remain ongoing and below is the most recent update from CityFibre following yesterday’s investigations:
Our night shift NOC team has informed us that it looks like the LSP flapping occurred again overnight at just after 02:00. It was also found that the LSP appears to flap once the physical flaps, the LSP tunnels follow suite.
An update from Ciena has been chased throughout the night, however we have received requests from Nokia (hardware supplier for core devices) to run some debug commands as well as answer a few of their questions with the assistances of our Architecture and Engineering team.
I have asked for this to be liaised with them as a matter of urgency given the matter at hand. This will be the main focus for today as to ensure that we have as much details to speak to Nokia with as possible.
We will update you further when we know more.
08:45
We are aware of an issue causing intermittent short drops in service for a small number of CityFibre services usually lasting 1-2 minutes. We first noticed this issue over the weekend and have been investigating with CityFibre since who are working on a resolution.
In most cases where we are seeing a drop if a backup broadband circuit is in place it is enough to trigger a failover event.
We will update you further when we know more.
10:20
We have received a further update from the supplier who believes this issue now resolved:
The switch is now back from the reboot and we are seeing traffic and routing back as it should be – we will investigate further the cause here as a background task to ensure it does not re-occur.
We did see some services drop due to the reboot and then come back up.
If your service was affected and has not been restored as of yet please reboot any related CPE in the first instance. If issues still persist please contact our Support Team via usual channels
09:45
We are aware of a possible issue that may affect some services with one of our suppliers:
We are currently seeing an issue with some traffic routing via Telehouse West – we currently believe one of our core switches has a forwarding issue,
Our NOC team are currently working to resolve this which MAY involve a brief reboot of the affected switch – causing a short downtime for services directly connected to that switch
We apologise for the brief and short notice reboot but want to resolve the issue as quickly as we can
We will update you further when we know more.
20:45
We have been monitoring services over the weekend and today and so far the network has remained stable.
The supplier remains cautious and will be continuing to monitor the network for any further issues for at least the next few days.
We are aware of a small number of websites that for certain customers are not accessible and are working with those customers and the supplier’s NOC team directly to resolve.
If your service was affected and has not been restored as of yet please reboot any related CPE in the first instance. If issues still persist please contact our Support Team via usual channels
16:45
We have received the below update from the supplier:
A considerable amount of changes and work has been completed during the day today including additional upstream capacity and changes to the filtering to protect our network. There is ongoing changes and updates ongoing this evening to bring the network stability back to what we would expect to provide our customers with.
Our technical team have also been in touch with the supplier directly and understanding more about the work still ongoing believe issues should be largely resolved this evening assuming all goes well.
We will be monitoring this issue this evening and will provide further updates as they become available.
Once again we apologise for the ongoing issues.
13:30
To the follow-up from the drop this morning, this is currently being worked on by the supplier’s senior team, the up-stream NOC team & the transit providers to ascertain what occurred and resolve fully.
In the meantime to get things back to a working state for most customers they have had to roll back some of the changes they’d previously made which has effected some of the mitigations for SIP and VPN traffic. They are working on restoring these as quickly as possible.
We are aware some customers still have lingering issues outside of SIP/VPN traffic and these are being looked into on a case by case basis.
We will update further when we know more and apologise for the ongoing issues.
09:45
We are aware another drop on services has just occurred.
We have reported this to the supplier and are waiting for an update as to what has caused it. We will update further when we know more.
Once again, we apologise for these ongoing issues.
08:00
The last update we received on this from the supplier last night indicated work was still ongoing to re-route affected traffic with the upstream transit provider overnight and to expect a further update this morning.
As soon as we have received this we will update further. Please note there may be some delay between us receiving an update from a supplier and being able to pass it on to customers.
18:45
Please see most recent update from supplier below on this issue:
Good evening. We are are working with the senior teams at the up-stream provider who have moved a large amount of the traffic that was being affected away from the routes. We are seeing improvements in the situation but we are also aware that some of our customers are still impacted.
We will update further when we know more. Please note there may be some delay between us receiving an update from a supplier and being able to pass it on to customers.
16:30
We are aware of some services still experiencing lingering issues and the supplier has confirmed they are related to this outage. They are working on trying to resolve these remaining issues and have provided the following update:
We have seen some improvement to services since our last update but just to confirm that we are still working on mitigation of the transit problems with the upstream provider; once we have a better view on timings etc we will add a further update here and in any event, one at 6PM.
We will update further when we know more. Please note there may be some delay between us receiving an update from a supplier and being able to pass it on to customers.
15:15

14:00
Within about 45 minutes of issues reoccurring we saw them settle back down again and services begin to return to normal, we are currently monitoring whilst we await a further update from the supplier.
We will update further when we know more.
12:30
Unfortunately we have seen a re-occurrence of this issue on our monitoring and the supplier has confirmed it appears the same upstream transit provider is once again having issues:
Our apologies; one of our up-stream transit providers is warning of route instability again. We were told this had been resolved but are actively working with them to understand why this had recurred and mitigate the cause. Our sincere apologies.
We will update further when we know more.
20:30
We have received a further update on this issue from our suppliers who have confirmed this should now be resolved. They are seeing traffic flowing normally again and are not seeing any lingering issues. From our own limited testing we also are not seeing any lingering issues.
As mentioned previously this issue was caused by a fault with an upstream transit supplier which affected multiple services.
If your service was affected and has not been restored as of yet please reboot any related CPE in the first instance. If issues still persist please contact our Support Team via usual channels.
16:30
We have received a further update on this issue and work is still ongoing to fully resolve and re-route affected traffic. Most services have come back online with minimal lingering issues and those that are still affected are largely seeing only intermittent packet loss. Currently whilst a firm ETA has not been given, we have been told to expect issues to be fully resolved sometime this evening and will be continuing to monitor the situation.
Issues may manifest as intermittent or permanent loss of service. In the case of Phone services this could also manifest as poor call quality.
We will update you further when we know more.
15:00
We have received a further update on this issue and now know the issue is with an upstream transit provider affecting multiple services. Suppliers are working to mitigate and route around. This is why the issue appears to be intermittent and for some customers is no longer affecting them.
Issues may manifest as intermittent or permanent loss of service. In the case of Phone services this could also manifest as poor call quality.
We will update you further when we know more.
14:30
We are aware of an outage affecting various internet based services since about 14:00.

We have received a further update from the supplier who now believes this issue fully resolved, please see below:
Once again, please accept our apologies for the problems you’ve seen over the previous couple of days. We realise that this has caused you all serious issues and for that, we’re very sorry.
Various internal changes have been implemented over the last 48 hours and currently, we believe that the network and associated services are now stable and will remain that way. We continue to monitor the situation closely to ensure that our network remains stable and there’s no further impact to your services.
Currently from what we can see services appear to have returned to normal and look to be stable and have been for some time now. This issue as previously mentioned was due to a large scale DDoS (Distributed Denial of Service) attack against one of our supplier’s networks.
If your service was affected and has not been restored as of yet please reboot any related CPE in the first instance. If issues still persist please contact our Support Team via usual channels.
16:30
We are once again seeing services start to settle down again and stabilise.
We are continuing to monitor the situation.
We will update here further when we know more.
15:30
We are aware that after a period of relative stability over the last few hours another drop has occurred.
The supplier is aware and working to resolve.
Unfortunately the DDoS attack that is the cause of these issues has not stopped in its intensity since it began yesterday and as a result the increased load on the network is causing intermittent drops and issues.
We will update you as soon as we know more.
10:00
We are aware service has gone down again and the supplier is investigating:
We are aware of issues still ongoing; we are actively working on these as before to mitigate their effects. We don’t have an ETA at the moment but we will update as soon was we do.
We will provide further updates as soon as we know more.
09:00
The supplier continued to apply mitigations works overnight and are monitoring the situation today. So far this morning we are seeing services remain stable.
A further update is expected by midday.
We will update further when we have received this.
16:45
We have received a further update from the supplier on this issue.
The DDoS attack itself is still occurring but the supplier is continuing to implement remediation works to reroute traffic and alleviate the load on the network. As such we have seen a number of services come back online however issues are still expected until the DDoS is fully mitigated.
We will continue to provide updates as we know more.
15:00
We are aware this issue remains ongoing and the supplier is working on resolving.
We apologise for the delayed update, the outage is affecting our access to certain services and systems and we are working on putting workarounds in place where possible to keep everyone up to date.
Our support desk ticketing system remains largely unaffected at this time but there is a backlog of requests from the outage slowing our responses there and we are doing our best to clear this backlog and update everyone.
We will update when we know more.
14:00
The supplier has advised they now believe this issue resolved and we are seeing services return to normal for affected customers.
Please see below update from the supplier:
We are seeing most services recovering. The attack target remains offline but we believe that this incident is now contained. We apologise again for this interruption in service. If you are still seeing issues, please restart your equipment.
This issue as previously mentioned was due to a large scale DDoS (Distributed Denial of Service) attack against one of our core supplier’s network.
If your service was affected and the issue is not resolved please get in touch with our support team via the usual channels.

We are monitoring for any further issues.
14:30
We have discussed this issue further with CityFibre and received clarity on the workaround that has been put in place.
After extensive testing they believe the issue appears to be with some of the Fibre ports on one of the Core Routers itself and so they have moved the effected links to alternative known good ports on the router. As such there should be no noticeable impact to service or reliability going forward from this.
CityFibre will continue to investigate the problematic ports and will look to reintroduce these into production at a later date if/when the issues with them have been resolved and extensively tested prior to doing so. This will be part of planned scheduled maintenance at a later date.
As such this issue is considered resolved.

Current status: After further review of the captured data, we’ve determined that a recent authentication change has introduced a problem where users with multiple accounts are unable to authenticate to the service properly, preventing them from accessing their mailboxes. We’re working to develop a fix to address this issue and will provide an estimated timeline for mitigation early next week.
Scope of impact: Users may experience this issue if they operate multiple related and trusted Enterprise log-in accounts across Microsoft 365 and Windows.
Root cause: A recent authentication change has introduced a problem where users with multiple accounts are unable to authenticate to the service properly, preventing them from accessing their mailboxes.
Microsoft have also advised the following workaround may restore access to Outlook in the interim:
1) Close Outlook and other Office applications.
2) Open an Office desktop application, such as Word, PowerPoint or Excel.
3) Navigate to File > Account > Switch accounts, and then click the ellipsis next to the account that’s not having the problem.
4) Click Sign out and then OK. *Note: Users that have multiple accounts may find it difficult to determine which account to sign out of; though, they should be able to sign back in later if there is an issue with this process.
5) Close the Office application used for this process and re-start the Outlook desktop client.
6) When prompted for a password, click “sign in to a different account” and enter the correct information.
If the above does not work users will need to revert to using Webmail as previously advised.
We are aware of an issue affecting Users on Office 365 ability to use Outlook to send and receive email. Please see details from Microsoft below:
User Impact: Users with multiple enterprise sign-in accounts can’t connect to Exchange Online via the Outlook desktop client. Users experiencing this problem will see the Outlook desktop client showing as disconnected and may receive the following error when attempting to send mail: “Sending and receiving reported error (0x80040115). The connection to the Microsoft Exchange Server is unavailable. Outlook must be online or connected to complete this action.”
Users may be able to leverage one of the following options to circumvent impact for this event:
– Affected users may be able to use Outlook on the web or mobile clients to access their mailboxes.
If you are being affected by this issue please attempt to use Outlook Webmail for the time being until Microsoft resolve the issue.
To access Outlook for the Web browse to https://outlook.office365.com and login with your Office 365 Email Address/Username and Password.

2G, 3G, and 4G data back online.
If customers are still experiencing issues reconnecting to mobile data, please advise them to turn their handsets off and on again (or turn flight mode on and then off). This will refresh the service and trigger it to actively search for a data signal.
Please advise any customers experiencing slow or intermittent data access that this may be down to the large number of customers reconnecting to data at the same time.
Thank you for your patience and understanding.

Apologies for the late notice but we have just received the notice below from our cloud service provider. There will be emergency maintenance late tonight to perform essential maintenance.
If you have any questions related to this please contact our helpdesk.
Effected systems: Virtual Private Cloud, questMail, VPS, questCloud Virtual Desktop
Description of works: We are currently experiencing an issue across our primary Hyper-V Clusters with Windows Remote Management Instrumentation (WinRM). This is effecting our ability to communicate with our Host Clusters and provide management access to customers. Some of the primary tasks WinRM provides are Virtual Machine load balancing across the clusters, Virtual Machine Migration, console management and storage management.
After consulting with the manufacturer of the software Microsoft we have been advised that the next course of action is to perform restarts of every node in our Host Clusters. Under normal operations this would not be an issue however, one of the effected systems of this fault is our ability to “Live Migrate” Customer Virtual Machines from one Host to another.
As a result of this completing this maintenance will effect service while each node is restarted.
Impact Details: Each Cluster Node will have its Virtual Machine guests placed into a “saved” or “paused” state then the node will be restarted and the guest Virtual machines resumed. During this time the Virtual machine will be unavailable, once the Virtual Machine is resumed it will continue from where it was before maintenance began without being restarted.
Service will be removed at 22:00 this evening and we are forecasting a restore of all services by 02:00, however it may be necessary to extend this until 04:00 in a worst case scenario.
We have been informed by City Fibre that between 06:00 and 15:00 on Sunday 27/11/16 Peterborough City Council are committed to completing the upgrade of their power distribution in the Town Hall. There should be no disruption of service, however due to the nature of the maintenance services are deemed “at risk” for the duration of this period. In the event of an outage and your service not automatically being restored you may need to restart both the white ONT & the supplied router or own equipment.
On Friday 4th November our office will be closing at 4pm.
Following the completion of our recent acquisition of Total Solutions and our continued dedication to providing the best service through a motivated and knowledgeable team we will be closing early on Friday 4th November 2016 for some team building.
It is important that all team members attend so from 4pm on Friday 4th November if you have an urgent support or maintenance issue please call in the usual way and follow the prompts, you will be asked to leave a message and one of our technical team will call you back shortly after the end of our meeting at 5pm.
If you have any other queries including non-urgent support queries from 4pm on Friday please email the relevant team or call on 01733 667755, leave a message and we will respond on Monday 7th November 2016.
If you have any questions please email getintouch@greencityict.co.uk
