Incident: PWAN Connectivity

We are aware of an incident affecting some PWAN connectivity. Engineers are already engaged and are investigating.

Further updates will be provided as and when they become available.

  1. Jordan Coleman says:

    Connectivity has now been restored. We apologise for any inconvenience caused.

    Reason For Outage: PWAN Connectivity

    Start: 7-Aug-2019 10:58
    Finish: 7-Aug-2019 11:13

    Impact: PWAN connectivity experienced a total loss of service (Primary and Backup) due to network loop affecting connectivity. Non PWAN connectivity was not affected.

    Root cause: Standard changes being implemented for a customer PWAN created unexpected impact due to pre-existing, redundant configuration on edge devices, triggering spanning tree to block connectivity to prevent a network loop.

    Additional actions:
    1. Edge devices config audit to check for, and if found remove, any redundant configuration under a maintenance window.
    2. Monitoring system event creation review to improve speed of identification of spanning tree activity.
