Update
Current status: We've begun returning a portion of the affected servers to service, and they're remaining stable so far. We’ve also shifted traffic and connections to alternative pathways wherever possible and have observed limited recovery in some regions.
Update
Microsoft 365 Update:
We've validated an alternative service health check method, which allowed a subset of affected servers to successfully return to service. We're now applying this change more broadly. We're also preparing automated recovery systems to continually detect and restart unresponsive servers, to maintain service stability while this change progresses. More info under EX1550543 and MO1550821 in the Microsoft 365 admin center, as well as status.cloud.microsoft if the admin center is not available to you.

Update
Update: Microsoft status- testing a configuration change to address a problem that's causing servers to fail automated health checks and become unavailable. In parallel, they've initiated a restart of all affected servers and are monitoring health as they return to service. More info under EX1550543
Investigating
Information Technology Services (ITS) is aware of an issue affecting some Microsoft 365. They are currently investigating an issue impacting multiple Microsoft 365 services and determined the affected infrastructure is experiencing elevated load across multiple regions, which is likely contributing to the connectivity errors.
Microsoft engineers began redistributing connection traffic across global infrastructure to balance the load and recover services. They will update the outage status once the outage is repaired.
Updates will be posted here as they become available.
