Failover to alternate infrastructure completed. Microsoft has switched to alternative healthy infrastructure to mitigate the impact of the outage. The company stated it has completed mitigation actions including failing over to alternate infrastructure and is continuing to monitor service health.

Elevated errors prompt further evaluation. As elevated error rates persist Microsoft is actively evaluating additional mitigation options. These options include optimizing how service requests are processed to further stabilize the service.
