[Intermittent] Degraded Access to Management Planes

This incident has been resolved.

A fix has been implemented and we are monitoring the results.

We've identified a related bottleneck where we're observing network congestion on the backend and we've formulated a plan to attempt to mitigate it. The management plane may still be unstable at this time until we've taken these full mitigation steps.

We are continuing to investigate this issue.

We are currently investigating an issue impacting multiple customers' ability to access their management plane instances. Attempts will sometimes result in 502 errors.

We will continue to update this post as more details become available.
