Incident with Actions, Pages, Pull Requests, Codespaces, API Requests, Issues, Webhooks and Packages
Incident
Report for GitHub
Resolved
From 16:24-16:43 UTC, multiple GitHub services were down or degraded due to an outage in one of our primary databases.
The primary host for a shared datastore for GitHub experienced an underlying file system write error which affected availability for the majority of public-facing GitHub services. SAML login was affected, as was access to Actions, Issues, Pull Requests, Pages, API, Webhooks, Codespaces, and Packages. In this case, our automatic failover was unable to handle the partial file system failure mode. We mitigated by manually performing a forced failover, initiated 17 minutes after our first alert and completed 2 minutes later.
With the incident mitigated, we are working to assess more detailed impact and resilience improvements to each impacted service while also improving the automated failover mechanism to support this scenario.
