Latest Message Title: Users with geolocation-based conditional access policies may be unable to access Microsoft 365 services

User impact: Some users with geolocation-based conditional access policies may be unable to access Microsoft 365 services.

More info: This issue affects organizations with geolocation-based conditional access policies applied and may cause tenant-wide sign-in disruptions to any Microsoft 365 service.

Current status: We’re continuing to redirect traffic from the affected regions to healthy infrastructure to mitigate impact. In parallel, we’re also continuing to revert the impacting change to the most recent unaffected configuration to fully remediate the issue. As these efforts continue, our telemetry and customer reports indicate that many customers are no longer experiencing impact. 

Scope of impact: This issue may affect any user in an organization with specific geolocation-based conditional access policies applied.

Start time: Thursday, March 23, 2023, at 3:00 AM UTC

Root cause: A recent update applied to a section of infrastructure responsible for regulating user geo-location may be inadvertently causing impact.
