Disruption with OpenAI Models
Resolved - On May 28th, 2026, between approximately 18:27 and 20:41 UTC, the GitHub Copilot service was degraded due to an issue with the Responses API of an upstream provider affecting the GPT-5.2, GPT-5.3-Codex, GPT-5.4, and GPT-5.5 models. Requests routed to these models via the Responses API returned elevated error rates, which also affected Copilot coding agent and Copilot code review. No other models were impacted.

We mitigated the incident by shifting traffic away from the affected models while the upstream provider deployed a fix.

GitHub is working to improve automated failover for the affected models and strengthen monitoring to prevent similar incidents in the future.
May 28, 20:41 UTC
Update - Open AI models are currently unavailable. We are shifting requests to other models to reduce impact.

Elevated error rates across multiple services
Resolved - On May 28, 2026, between 19:07 UTC and 19:16 UTC, multiple GitHub services experienced elevated error rates. This was due to a change that was partially deployed to an authentication service, causing errors for dependent services including the web experience, REST API, Git operations, and GitHub Actions. At peak impact, 10% of GitHub Actions runs failed to queue or encountered errors while downloading actions. We mitigated the incident by rolling back the change.

We are expanding test coverage and improving our deployment validation process to prevent recurrence of this issue in the future.
May 28, 19:07 UTC
Webhook APIs and UI Degraded
Resolved - On May 28, 2026, between 00:54 UTC and 01:19 UTC, some users experienced errors when interacting with the Webhooks API, including webhook delivery history and configuration endpoints. On average, the error rate was 0.28% and peaked at 0.45%. This was due to a bug that caused a single Kubernetes pod to enter a CrashLoopBackOff after receiving a 500 with an empty response body from Cosmos DB.

We mitigated the incident by restarting the service. To prevent future incidents, we are pushing a change to handle this response scenario from Cosmos DB appropriately.

Incident with Pull Requests, Issues, Git Operations and API Requests
Resolved - On May 27, 2026, between 12:07 UTC and 13:16 UTC, users experienced degraded performance for Git operations, Pull Requests, Issues, GraphQL API, and related services on github.com. During this time, operations that depended on Git file servers experienced elevated error rates (3.5% of pushes via HTTPS and 0.2% of pushes via SSH failed; no fetches/clones failed). An internal analytics component generated unexpectedly high load, which caused CPU saturation on the underlying infrastructure. This led to cascading slowdowns and errors across services that depend on Git operations. The issue was mitigated by stopping the offending component. Services began recovering shortly after mitigation and were fully restored by 13:16 UTC. We are taking steps to add resource limits and kill switches for internal analytics components to prevent similar issues in the future.

Disruption with some GitHub services
Resolved - On May 26, 2026, between 15:10 UTC and 16:35 UTC the Copilot service was degraded and many models were no longer available for use. On average, the error rate was ~5% and peaked at 11% of requests to the service. This was due to a change that introduced a configuration mismatch in HMAC signing credentials which caused the list of available models to be truncated. This was mitigated by rolling back the change. This rollback was complete by 15:34 UTC though users continued to see impact until cache TTLs expired.

We are working to improve our monitoring and error handling to reduce time to detection and better experience for issues like this in the future.

Incident with Actions and Pages
Resolved - On May 26, 2026, between 10:40 UTC and 12:56 UTC, GitHub Actions jobs were degraded. From 10:40 to 12:16 UTC, all newly queued Actions runs failed to start. From 12:16 to 12:56 UTC, Actions runs that required downloading actions for their workflows continued to fail. GitHub Pages, Copilot Code Review, Copilot coding agent, Octoshift, and GitHub Enterprise Importer were also impacted due to their dependency on Actions.

This was caused by our automated account review system incorrectly suspending the service account used by GitHub Actions to authenticate workflow runs and download actions.

We mitigated by restoring the account at 12:16 UTC, marking it exempt from further automated review at 12:20 UTC, and redeploying a related service at 12:48 UTC to flush cached account state. Full recovery was confirmed at 12:56 UTC.

During this incident, a small number of Issues, PRs, Comments, and Discussions were marked as hidden when the service account was disabled. No data was lost. All content hidden because of this incident has been restored and full search index restoration is in progress.

To prevent a recurrence, we have added an allowlist of all service accounts that cannot be suspended by automated systems, and ensuring these protections are enforced consistently across all account management tooling. We are also improving diagnostic tooling for accounts and reducing cache propagation delays to shorten time to mitigate similar incidents in the future.

Intermittent errors with app installation token authentication
Resolved - On May 23, 2026 between 06:00 UTC and 19:12 UTC, GitHub experienced intermittent errors authenticating GitHub app installation tokens.

During this time, between 1-5% of app installation token authentication requests failed, with an average of 2.3% and the error rate peaking at approximately 5.4% around 14:00 UTC. Users may have experienced authentication failures when using GitHub Apps, including failures in Git operations and API calls using app installation tokens.

The issue was caused by an issue in a caching proxy component and was remediated by rolling back that component to a previous version. We are taking steps to improve monitoring for cache miss anomalies to ensure that token authentication remains functional during infrastructure changes and reviewing our protocol for testing and when we upgrade third-party dependencies.
