On 2023-10-26, a failure in the rate limiting middleware for the Studio API denied access to rate-limited endpoints for a period of 8 minutes, during 04:12am and 04:20am.
A failover caused by a security update in the underlying storage system was not handled appropriately, and did not fallback to bypass rate limiting altogether.
We will implement an explicit bypass strategy on this rate limiting middleware so we can tolerate planned maintenance or other circumstances that prevent access to this state storage subsystem.
