Actions and Codespaces APIs experiencing partial failures

Updates

• resolved

  On July 7, 2026, between 14:01 UTC and 16:17 UTC the Actions and Codespaces REST APIs were degraded and returned intermittent 500-class errors for a percentage of requests. Error rates peaked at approximately 8% of Actions runner API requests and 13% of Codespaces API requests, though retries were frequently successful. In-progress Actions runs and Codespaces were not impacted and continued successfully. This was due to a recent change that did not deliver the expected performance and, under certain conditions, caused downstream errors.<br /><br />We mitigated the incident by rolling back the change, after which the affected services recovered.<br /><br />We are working to improve the resilience of our services to these conditions and to strengthen our monitoring to reduce our time to detection and mitigation of issues like this one in the future.
