Incident: Virgin Media Based Circuits

Posted: Tuesday, February 16th, 2016 at 12:57 by Scott Morgan

We are currently aware of an issue affecting a number of Virgin Media based circuits. We are working with our supplier who are now commencing investigation.

We will continue to work with our suppliers and publish updates as they become available.

  1. Scott Morgan says:

    We have identified this as affecting a single Virgin Media NTU impacting approximately 200 circuits.

    We are continuing to work closely with our suppliers in order to get the issue resolved and further updates will follow, as they become available.

  2. Ryan Berrisford says:

    Our suppliers are engaging and dispatching engineering resource to the point of presence in InterXion.

    An estimated time of arrival for the engineering resource will follow shortly, which will be updated via this post.

  3. Ryan Berrisford says:

    Further updates from our supplier have advised that the issue is located between InterXion and Brentford. Engineering resource is continuing to work on the issue and updates will follow as they become available.

  4. Conor Murphy says:

    Engineers are continuing to investigate the reported fault to isolate the issue further. We are keeping in constant contact with our suppliers and further updates will be posted as and when they become available.

  5. Ryan Berrisford says:

    Affected leased line have now been restored to normal service.

    We have been in contact with our supplier who have advised that although services have been restored, they will be considered at risk until the engineer has closed off the fault with his full findings.

    We are expecting full confirmation shortly and will update partners via this post.

  6. Conor Murphy says:

    Suppliers have confirmed service has been restored via a temporary work around to bypass a faulty fibre patch at the Poplar Metnet. Virgin Media will schedule future planned maintenance to fix the original fault.

    Services should no longer be considered at risk however we will update further once the planned maintenance to complete the repair has been scheduled.

  7. Ryan Berrisford says:

    Further to the incident yesterday, we have been in constant contact with our supplier to confirm the strategy for the planned maintenance.

    As the workaround in place no way diminishes the service we provide, it will remain in place for the foreseeable future whilst our supplier confirms the scheduled dates for the maintenance. The maintenance will then be notified to us via the normal change management channels so we can inform our customers.

    A full incident report has been requested from our suppliers which will be published as and when we receive it.

    We apologise the inconvenience caused during the course of yesterday afternoon.

  8. Scott Morgan says:

    After extensive correspondence with our supplier, developments within the Virgin Media network have deemed further fibre work is required between 2 different Virgin Media Transmode Muxes in the Poplar exchange. As the further work is critical to the service, a director level decision has been made to carry out emergency maintenance and this has been scheduled for tonight, out of business hours.

    The maintenance window is 18/02/2016 00:01 – 06:00. Virgin Media have advised the maximum amount of downtime is classed as 4 hours, although downtime for Entanet is expected to be much less.

    All customers with an ADSL backup service will failover and continue to work during this period.

    We apologise for the short notice and we will work with our suppliers to keep downtime to a minimum.
