Title: Some users may have been unable to access Microsoft OneDrive content and may have noticed delays or navigation errors

User impact: Users may have been unable to access OneDrive content and may have noticed delays or navigation errors.

Final status: We’ve confirmed, following a period of monitoring service telemetry, that redirecting user traffic to alternate infrastructure successfully resolved the issue.

Scope of impact: This issue impacted internal Microsoft users only.

Start time: Sunday, July 12, 2026, at 10:20 AM UTC

End time: Sunday, July 12, 2026, at 10:44 AM UTC

Root cause: A section of SQL database infrastructure is performing below acceptable performance thresholds and resulting in impact.

Next steps: We're analyzing performance data and trends on the affected infrastructure to help prevent this problem from happening again.

This is the final update for the event.
