    A post-incident report has been published.

  2. Oct 13, 2026, 20:54 CEST

    We've completed our restarts throughout the affected infrastructure and confirmed through telemetry and user reports that this issue is resolved.

  3. Oct 13, 2026, 20:18 CEST

    We're finishing our restarts throughout the affected infrastructure and expect this will be complete and resolve all impact by Tuesday, October 13, 2026, at 7:00 PM UTC. Our telemetry is showing service recovery, and we'll continue to monitor to ensure full remediation.

  4. Oct 13, 2026, 19:56 CEST

    As a workaround, users may disable GSA to access the affected Microsoft 365 services until the resolution of this incident.

    This quick update is designed to give the latest information on this issue.

  5. Oct 13, 2026, 19:23 CEST

    We're continuing our targeted restarts throughout the impacted infrastructure, and our telemetry shows services hosted on the restarted infrastructure are now operating at healthy service levels. We're also receiving confirmation that impact is resolved for some users.

  6. Oct 13, 2026, 18:22 CEST

    We're restarting a portion of impacted infrastructure where we've removed traffic and are seeing positive trends towards recovery. We've confirmed through internal testing that this resolves impact for some users and we're monitoring to validate the full recovery of the service.

  7. Oct 13, 2026, 17:21 CEST

    We've completed redirecting traffic to healthy infrastructure and are assessing for positive trends towards recovery. We're continuing to investigate additional mitigating actions to expedite remediation.

  8. Oct 13, 2026, 16:57 CEST

    We're redirecting traffic from the underperforming infrastructure to improve service health. We're monitoring to confirm this will fully resolve impact.

    This quick update is designed to give the latest information on this issue.

  9. Oct 13, 2026, 16:35 CEST

    We've deployed the traffic optimizations and although we saw a reduction of errors initially, this did not fully resolve the issue. We're continuing to troubleshoot the issue to develop additional mitigation strategies.

  10. Oct 13, 2026, 15:29 CEST

    We're continuing to apply the aforementioned traffic and performance optimizations with early signals showing signs of recovery.

  11. Oct 13, 2026, 13:30 CEST

    We’ve identified that a section of GSA infrastructure is performing below acceptable performance thresholds, affecting connectivity to Microsoft 365 services and resulting in impact. We’re applying performance and traffic optimizations to remediate impact and restore connectivity.

  12. Oct 13, 2026, 11:41 CEST

    We're reviewing service monitoring telemetry to isolate the source of the issue and establish a fix.

To see whether your own tenant is affected, check Service health in the Microsoft 365 admin center. Only a backup outside Microsoft protects against data loss, and only a tested break-glass account against locked-out admins. We set up both in fixed-scope sprints.

This is the view of a Swiss Microsoft 365 tenant: services not licensed there are missing, and individual issues may affect your tenant differently. Microsoft names the region only in the issue text. The Switzerland view shows issues for Switzerland, for Europe in general and those without a region, but not issues that only name other countries such as Germany or the UK.
