[Retroactive] Actions workflow run failures after deployment gate approvals
Resolved - On October 1, around 02:00 UTC, an isolated infrastructure failure caused GitHub Actions to lose execution state for a small number of existing workflow runs. Affected runs may remain stuck, fail deployment approvals, or return errors when cancelled. Service connectivity has recovered, but the lost state cannot be restored by retrying an approval.


If you're affected, you can trigger a new run or contact GitHub Support with links to your stuck runs so we can unblock them. Once cleared, select "Re-run all jobs." This preserves the workflow run ID but starts a new attempt, rebuilds artifacts, and requires fresh deployment approvals. Before rerunning, check whether any deployment steps already completed to avoid repeating changes.

Copilot Code Review is unable to complete reviews
Resolved - On September 28, 2026, between 19:23 UTC and 22:08 UTC the Copilot Code Review service was degraded and pull request reviews did not complete in all environments. On average, approximately 70% of requested reviews did not complete. Reviews requested during this window were not automatically retried, and users needed to re-request a review from their pull request. This was due to a change in a dependent service that stopped delivering data Copilot Code Review needs to complete a review. Review completion is an inherently delayed signal, because each review job takes time to start and finish, so it took longer to detect the impact.

We mitigated the incident by reverting the change.

We are working to add a faster signal for reviews that fail to complete, add deployment validation that confirms a Copilot Code Review completes end to end, improve how we track internal dependencies between services, and make our deployment pipeline more reliable to reduce our time to detection and mitigation of issues like this one in the future.
Sep 28, 22:08 UTC
Update - Copilot Code review has recovered, for reviews that were previously not successful you can re-request review from your PR.
Sep 28, 22:08 UTC

Disruption with billing information updates
Resolved - Beginning on September 22, 2026 at 11:51 UTC, approximately 1,700 users experienced delays and errors when adding or updating billing address information because requests to the address validation service timed out or failed. Within the affected address validation flow, requests failed at an average rate of 69.3%, reaching 100% at peak.

An operating system upgrade exposed a compatibility issue in an adapter used by our HTTP client library, causing requests to stall. A subsequent change to shorten request timeouts caused stalled requests to return connection errors and increased the failure rate.

We mitigated the incident on September 24, 2026 at 20:24 UTC by changing the HTTP client used for address validation. We have added alerting to detect similar issues sooner and are extending the fix to other integrations.

Incident across several services
Resolved - Starting at 07:57 UTC on September 23, GitHub experienced elevated 500 and 404 responses across several application pages. This caused failures when installing GitHub Apps, creating organizations, and making some organization membership changes. Customers also experienced delayed label updates and stale search results in Projects.

The infrastructure failure was isolated to our Azure Central US region. The API errors were mitigated by 10:58 UTC on September 23. Projects' processing continued to recover while an accumulated backlog was drained, and full service was restored at 04:55 UTC on September 24.

The incident was caused by a failed planned maintenance operation on a primary database. Automated recovery initiated an emergency database failover, after which several replicas in the affected region were unable to resume replication correctly. This reduced available database capacity and caused the API errors and downstream Projects processing delays.

We have mitigated the immediate failure mode. We are also improving maintenance safety checks, database failover handling, post-failover replica validation, and downstream processing resilience to reduce the likelihood and impact of similar incidents.

Incident with Pull Requests
Resolved - On September 20, 2026, between 21:46 and 22:24 UTC the Pull Requests service was degraded and pull request merge and test-merge commits were created late, with delays reaching approximately four minutes at peak. Merge commits were delayed rather than lost. Because some Actions workflow runs start only after a pull request's merge commit is created, a subset of workflow runs for pull request events were also delayed.

This was due to a routine repository maintenance job for an unusually large repository consuming nearly all of the memory on a single Git storage server, which left that server unable to serve the Git operations used to create merge commits.

We mitigated the incident by removing the affected server from service at 22:18 UTC, after which the queued merge commits were created within six minutes.

We have capped the memory a single repository maintenance job may consume so that one repository cannot exhaust a server, and we have improved monitoring and alerting on storage server health to reduce our time to detection and mitigation of issues like this one in the future.
Sep 20, 23:22 UTC
Update - A git fileserver issue caused a brief delay in creating some merge commits - we've isolated the underlying server and already observed recovery.

Elevated rate of errors for OpenAI models provided by Copilot
Resolved - Between 20:26 and 21:17 UTC on September 17, 2026, GitHub Copilot experienced degradation affecting several GPT models, including GPT-5.6 Luna, GPT-5.6 Terra, GPT-5.6 Sol, GPT-5.3-Codex, and GPT-6 Astra. Users encountered elevated error rates when using these models.

The degradation was caused by an issue with an upstream model provider. GitHub engineers detected the issue through automated monitoring and coordinated with the provider. Our automated model-warning system activated in-product warnings for affected models during the incident. Service returned to normal after the provider implemented a mitigation.
Sep 17, 21:49 UTC
Monitoring - We are experiencing degraded availability for GPT-5.6 Luna, GPT-5.6 Terra, GPT-5.6 Sol, GPT-6 Astra, GPT-5.3-Codex in Copilot products and IDE surfaces. This is due to an issue with an upstream model provider. The provider is working to mitigate the problem and we are monitoring recovery. We recommend choosing another model or selecting 'Auto' to continue using Copilot.
