During network upgrade maintenance at our LON1 datacenter, a legacy device was not cleanly decommissioned before disconnection, causing an abrupt drop in traffic routed through it. The network required failover to alternative routes and propagation restart, which took approximately 40 minutes.
During this window, LON1 host node service dashboards and the service console were unavailable. Connectivity routed through the affected device was disrupted.
All services have been fully restored as of 3:09 AM (GMT+8). We will be reviewing our maintenance procedures to ensure legacy devices are properly drained and verified before disconnection in future upgrade windows to prevent recurrence.
We sincerely apologize for the disruption and thank you for your patience.
