On October 14th, 2025, between 18:26 UTC and 18:57 UTC a subset of unauthenticated requests to the commit endpoint for certain repositories received 503 errors. During the event, the average error rate was 3%, peaking at 3.5% of total requests.
This event was triggered by a recent configuration change and some traffic pattern shifts on the service. We were alerted of the issue immediately and made changes to the configuration in order to mitigate the problem. We are working on automatic mitigation solutions and better traffic handling in order to prevent issues like this in the future.

On Oct 14th, 2025, between 13:34 UTC and 16:00 UTC the Copilot service was degraded for GPT-5 mini model. On average, 18% of the requests to GPT-5 mini failed due to an issue with our upstream provider.
We notified the upstream provider of the problem as soon as it was detected and mitigated the issue by failing over to other providers. The upstream provider has since resolved the issue.
We are working to improve our failover logic to mitigate similar upstream failures more quickly in the future.

On October 9th, 2025, between 14:35 UTC and 15:21 UTC, a network device in maintenance mode that was undergoing repairs was brought back into production before repairs were completed. Network traffic traversing this device experienced significant packet loss.
Authenticated users of the github.com UI experienced increased latency during the first 5 minutes of the incident. API users experienced up to 7.3% error rates, after which it stabilized to about 0.05% until mitigated. Actions service experienced 24% of runs being delayed for an average of 13 minutes. Large File Storage (LFS) requests experienced minimally increased error rate, with 0.038% of requests erroring.
To prevent similar issues, we are enhancing the validation process for device repairs of this category.

Between 13:39 UTC and 13:42 UTC on Oct 9, 2025, around 2.3% of REST API calls and 0.4% Web traffic were impacted due to the partial rollout of a new feature that had more impact on one of our primary databases than anticipated. When the feature was partially rolled out it performed an excessive number of writes per request which caused excessive latency for writes from other API and Web endpoints and resulted in 5xx errors to customers.
The issue was identified by our automatic alerting and reverted by turning down the percentage of traffic to the new feature, which led to recovery of the data cluster and services.
We are working to improve the way we roll out new features like this and move the specific writes from this incident to a storage solution more suited to this type of activity. We have also optimized this particular feature to avoid its rollout from having future impact on other areas of the site. We are also investigating how we can even more quickly identify issues like this.

On October 7, 2025, between 7:48 PM UTC and October 8, 12:05 AM UTC (approximately 4 hours and 17 minutes), the audit log service was degraded, creating a backlog and delaying availability of new audit log events. The issue originated in a third-party dependency.
We mitigated the incident by working with the vendor to identify and resolve the issue. Write operations recovered first, followed by the processing of the accumulated backlog of audit log events.
We are working to improve our monitoring and alerting for audit log ingestion delays and strengthen our incident response procedures to reduce our time to detection and mitigation of issues like this one in the future.
