Identified
Microsoft's investigation has found that a process on the affected servers responsible for establishing secure connections becomes overwhelmed, causing the servers to stop processing requests. Microsoft is preparing a configuration change to address this behavior that can be applied across all affected servers, and they're validating it on a subset of servers before applying it more broadly alongside restarts of the affected infrastructure. In parallel, Microsoft begun reverting a recent network configuration change that correlates with the start of impact and are monitoring to determine whether this contributes to recovery. The temporary traffic limitations Microsoft previously described at https://status.cloud.microsoft/m365/referrer=serviceStatusRedirect are now in effect in specific locations. They are monitoring the affected servers in those locations to confirm whether they remain stable while handling a narrower set of connections, after which they'll gradually reintroduce additional traffic.
