Disruption with some GitHub services

Resolved - On June 18, 2025 between 22:20 UTC and 23:00 UTC the Claude Sonnet 3.7 and Claude Sonnet 4 models for GitHub Copilot Chat experienced degraded performance. During the impact, some users would receive an immediate error when making a request to a Claude model. This was due to upstream errors with one of our model providers, which have since been resolved. We mitigated the impact by disabling the affected provider endpoints to reduce user impact, redirecting Claude Sonnet requests to additional partners.

We are working to update our incident response playbooks for infrastructure provider outages and improve our monitoring and alerting systems to reduce our time to detection and mitigation of issues like this one in the future.
Jun 18, 23:13 UTC

Update - We are experiencing degraded availability for the Claude 4 model in Copilot Chat, VS Code and other Copilot products. This is due to an issue with an upstream model provider. We are working with them to resolve the issue.

Other models are available and working as expected. We recommend using Claude 3.7 as an alternative.
Jun 18, 22:42 UTC

Update - Copilot is experiencing degraded performance. We are continuing to investigate.

Partial Actions Cache degradation

Resolved - On June 18, 2025, between 08:21 UTC and 18:47 UTC, some Actions jobs experienced intermittent failures downloading from the Actions Cache service. During the incident, 17% of workflow runs experienced cache download failures, resulting in a warning message in the logs and performance degradation. The disruption was caused by a network issue in our database systems that led to a database replica getting out of sync with the primary. We mitigated the incident by routing cache download url requests to bypass the out-of-sync replica until it was fully restored.

To prevent this class of incidents, we are developing capability in our database system to more robustly bypass out-of-sync replicas. We are also implementing improved monitoring to help us detect similar issues more quickly going forward.
Jun 18, 18:47 UTC

Update - We are continuing to rollout a mitigation and are progressing towards having this rolled out for all customers.
Jun 18, 18:11 UTC

Update - We are currently deploying a mitigation for this issue and will be rolling it out shortly. We will update our progress as we monitor the deployment.
Jun 18, 17:22 UTC

Update - We are actively investigating and working on a mitigation for database instability leading to replication lag in the Actions Cache service. We will continue to post updates on progress towards mitigation.
Jun 18, 17:03 UTC

Update - The actions cache service is experiencing degradation in a number of regions causing cache misses when attempting to download cache entries. This is not causing workflow failures, but workflow runtime might be elevated for certain runs.

Partial Degradation in Issues Experience

Resolved - On June 18, 2025, between 15:15 UTC and 19:29 UTC, the Issues service was degraded, and certain GraphQL queries accessing the `ReactionGroup.reactors` field returned errors. Our query routing infrastructure was impacted by exceptions from a particular database migration, resulting in errors for an average of 0.0097% of overall GraphQL requests (peaking at 0.02%).

We mitigated the incident by reverting the migration.

We continue to investigate the cause of the exceptions and are holding off on similar migrations until the underlying issue is understood and resolved.
Jun 18, 17:42 UTC

Update - We have confirmed that we are currently within SLA for Issues experience. Remaining clean up will complete over the next few hours to fully restore the ability to search Issues by reaction as well as related GraphQL API queries.
Jun 18, 17:41 UTC

Update - We have confirmed that impact is restricted to failing to display reactions on some issues and searching issues by reaction. Mitigation is in progress to restore these features and should be fully rolled out to all customers in the next few hours.
Jun 18, 17:07 UTC

Update - Some users are seeing errors when accessing issues on GitHub. We have identified the problem and are working on a revert to restore full functionality.
Jun 18, 16:25 UTC

Incident with multiple GitHub services

Resolved - On June 17, 2025, between 19:32 UTC and 20:03 UTC, an internal routing policy deployment to a subset of network devices caused reachability issues for certain network address blocks within our datacenters.
Authenticated users of the github.com UI experienced 3-4% error rates for the duration. Authenticated callers of the API experienced 40% error rates. Unauthenticated requests to the UI and API experienced nearly 100% error rates for the duration. Actions service experienced 2.5% of runs being delayed for an average of 8 minutes and 3% of runs failing. Large File Storage (LFS) requests experienced 0.978% errors.
At 19:54 UTC, the deployment was rolled back, and network availability for the affected systems was restored. At 20:03 UTC, we fully restored normal operations.
To prevent similar issues, we are expanding our validation process for routing policy changes.
