SUMMARY OF IMPACT: Starting at approximately 19:15 UTC on 15 Mar 2021, some customers may experience issues authenticating into Microsoft services, including Microsoft Teams, Office, Dynamics, Xbox Live, and the Azure Portal. Other Azure services that rely on authentication infrastructure downstream may see further impact.
CURRENT STATUS: We have completed rollout of a fix addressing the Azure Active Directory underlying cause, mitigating impact to Azure Active Directory and the Azure Portal. Some customers may be seeing preliminary signs of recovery.
At this time, a subset of Azure services may be experiencing residual impact due to downstream impact to Azure Storage and Azure Key Vault services; These services are continuing to pursue recovery actions.
