[Mitigated Sep 4] Customers unable to authenticate to Azure AD B2C


Between 0930h and 1800h UTC,  A very small set of Azure AD B2C Directory administrators experienced intermittent failures accessing the Azure AD B2C blades and some end-users had intermittent failed authentications.  Users who retried, were likely able to authenticate and access the protected resources.  The issue has been mitigated.

Only a few B2C tenants were impacted with small impact to end users.

We apologize for the inconvenience. If you have any additional insights/repro, please communicate with us on AADB2CPreview@microsoft.com.
