On July 22nd, 2020, at approximately 12:27 UTC, our monitoring reported issues with connectivity in our London data center. A prompt investigation revealed the cause to be a suspended port-channel between a customer aggregation switch and our core routers resulting in network instability for Linodes attached to this switch despite the built in redundancy. Once identified, the interfaces were removed from the suspended state immediately. All affected services were restored at approximately 12:41 UTC. We have engaged our switch vendor to investigate the cause of the port-channel unexpectedly being suspended, and have added an additional interface to the port-channel for increased stability.
