At Risk: Telford-dc3.core

Posted: Monday, November 20th, 2017 at 14:03 by Iain Beveridge

Tuesday 28th November 2017 23:50 – Wednesday 29th November 2017 06:00 

During the above window we will be tidying the cabling inside our cabinets in preparation of the installation of replacement hardware in the near future.

No down time is expected and all precautions will be taken to avoid any disruption, however during this time any customers directly connected to this core should be considered at risk.

Planned Maintenance: Peterborough

Posted: Monday, October 30th, 2017 at 16:26 by Mark Yardley

Wednesday 8th November 2017 00:01 – 06:00

During the above window we will be replacing equipment at this site with a higher capacity router.

All services currently terminated in this location will be migrated on to the new hardware. This includes all DSL, EWCS, leased lines and wholesale circuits at this location.

All other traffic that would normally route through this location will take alternative paths.

    This work is now complete.

Incident: Cardiff Edge Device

Posted: Wednesday, October 25th, 2017 at 18:20 by Richard Partridge

We have just experience an unexpected reload of one of our edge devices in Cardiff. This resulted in a brief loss of service for directly terminated leased line customers. Initial investigations suggest this was a brief power failure. This has been reported to our colocation provider for further investigation.

Incident: Nottingham Core

Posted: Monday, October 23rd, 2017 at 19:08 by Richard Partridge

We’ve just experienced an unexpected reload of the nottingham.core router. Engineers are investigating and this has been raised with our colocation provider as well. Further updates will be provided as and when they become available.

Incident: colindale.core

Posted: Monday, October 16th, 2017 at 09:04 by Alistair Patterson

Our core router in Colindale has unexpectedly rebooted. All services appear to have recovered, investigations are underway to determine the cause.

An engineer has been dispatched to site.

Further updates to follow when available.

  1. Adam Heath says:

    Our investigations confirm this incident as power related.

    We are working on root cause with our colocation provider, which is responsible for delivering our power, UPS, power monitoring and alerting at these locations.

    This remains at our highest priority and we are monitoring the situation closely.

Incident: cardiff.core

Posted: Tuesday, October 10th, 2017 at 18:08 by David Derrick

We have lost connectivity to our Cardiff router. Initial investigation suggests it is rebooting. We will continue to investigate and update when we know more.

  1. David Derrick says:

    The router has finished reloading and services are restored. We will continue to investigate the cause.

  2. Richard Partridge says:

    The cardiff.core router appears to have sustained another unexpected reload. Engineers are currently investigating. Further information will follow shortly.

  3. Richard Partridge says:

    Engineers are being dispatched to Cardiff to continue the investigation. Due to the number of recent failures, we are also planning to replace the core router whilst on site, which was originally planned for next week.

    Once engineers are on site and have assessed the situation, a notification outlining an emergency maintenance window will be published. The site should be considered at-risk until otherwise notified.

  4. Richard Partridge says:

    Engineers are on site and have concluded their initial investigation. Based on our findings we are currently proceeding with our plan to replace the core router this evening. A downtime window will be announced in due course.

  5. Richard Partridge says:

    We are planning to replace the Cardiff core router between 18:00 and 20:00 this evening. The core itself should be back online within 30 minutes during the window, however individual services will take longer to restore as they are migrated in turn from one core to the other.

  6. Jake Turner says:

    Further investigation on site within the maintenance window highlighted a fault with the power infrastructure that will be addressed by our colocation provider. We have taken measures to prevent further outages in the interim. As such the core router was not swapped.

Kingston Node

Posted: Thursday, September 28th, 2017 at 13:59 by David Brewis

We are currently noticing intermittent periods of packet loss on traffic passing through our Kingston node, affecting only ADSL services. This has been raised with BT for further investigation.

We will provide further information when it becomes available.

  1. David Brewis says:

    We have seen the levels return to normal but continue to discuss the case with BT

  2. David Brewis says:

    Following investigations an issue has been identified and steps have begun to to further identify the cause allowing for resolution.

  3. David Brewis says:

    Following changes on the incoming connection made by the supplier, we have not seen a repeat of the issue. Monitoring and investigations continue with updates published as made available.

Incident: Vodafone Circuits

Posted: Thursday, September 28th, 2017 at 08:32 by Alistair Patterson

We are currently aware of an issue causing a loss of connectivity for a number of Vodafone based Ethernet circuits. Our initial diagnostics indicate the issue to be on one of Vodafone’s hubs. A fault has already been raised with Vodafone and is under investigation.

Further updates will follow as they become available.

  1. Alistair Patterson says:

    Vodafone have confirmed engineers are expected to arrive at the fault site shortly to continue investigations.

    Further updates will be posted as soon as available.

  2. Alistair Patterson says:

    Vodafone engineers have resolved the issue and all services have been restored. Circuits should still be considered at risk until Vodafone clear the incident.

    Further information on the root cause and fix will be made available when received from Vodafone.

  3. Alistair Patterson says:

    This incident has now been cleared. Vodafone confirm an issue with a line card was resolved by their engineers.

    We apologise for the inconvenience caused during this incident.

At-Risk: Kingston to Slough fibre link maintenance

Posted: Wednesday, August 16th, 2017 at 07:38 by Iain Beveridge

21-Aug-2017 02:00 GMT to 21-Aug-2017 06:00 GMT

During the above window one of our fibre suppliers will be carrying out maintenance on one of our links between Kingston and Slough. Whilst the actual downtime is expected to be less, the full 4 hrs may be required to account for any unforeseen issues. This work is not expected to be service affecting, however, you may see unusual paths and increase in latency while traffic is automatically rerouted via alternate routes.

Email Disruption

Posted: Thursday, July 13th, 2017 at 10:15 by Richard Partridge

We are currently receiving reports that a small number of DSL customers are experiencing difficulty when trying to send or receive emails. Our engineers are currently investigating and further information will be provided as and when it becomes available.

  1. Richard Partridge says:

    Engineers are still investigating the email issue at this time. Further updates will be provided over the course of the day.

  2. Richard Partridge says:

    Engineers have now been able to recreate the symptoms being reported and are investigating a possible root cause of the problem. Further updates will follow in due course.

  4. Richard Partridge says:

    Adjustments have been made to try and resolve this problem, however we will need to return to normal bandwidth levels in order to determine their effectiveness. Further updates will be provided tomorrow morning once the impact of these changes have been ascertained.

  5. Richard Partridge says:

    “Yesterday’s adjustments have had a positive affect, but haven’t entirely resolved the problem. We’re continuing to work on this and will provide further updates over the course of the day.”

  6. Richard Partridge says:

    No further issues have been reported over the course of the afternoon. We will closely monitor the situation over the course of the weekend and advise of any further occurrences of this issue accordingly.
