Current status: We've validated an alternative health check method on a subset of affected infrastructure, which allowed the servers in that subset to successfully return to service, and we're now applying this change more broadly. We're also preparing an automated recovery process to continually detect and restart unresponsive servers, to help keep them in service while this change progresses. Additionally, our review of recent changes has identified a small number of configuration updates that we're investigating as potential contributors to the issue.

Microsoft is working to reduce the impact and has paused deployments and configuration changes while it reviews whether recent changes contributed to the issue. It has also redirected traffic for some services away from the affected infrastructure, with further traffic moves underway.
