## Timeline of updates

- **resolved** 2023-10-17 13:49 UTC: From 10:59 UTC to 13:48 UTC, GitHub Codespaces service was down or degraded due to an outage in our authentication service.This issue impacted 67% of users over this time period. Our service auth layer experienced throttling with our third party dependencies due to higher load. This impacted all user facing scenarios for Codespaces service. Our automated regional failover kicked in, but it failed to mitigate as this issue impacted the service globally. We mitigated manually by reducing load on external dependency. With the incident mitigated, we are working to assess and implement scaling improvements to make our service more resilient with increasing load.
