    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.
