Multiple services are affected, service degradation
On Mar 5, 2026, between 16:24 UTC and 19:30 UTC, Actions was degraded. During this time, 95% of workflow runs failed to start within 5 minutes with an average delay of 30 minutes and 10% workflow runs failed with an infrastructure error. This was due to Redis infrastructure updates that were being rolled out to production to improve our resiliency. These changes introduced a set of incorrect configuration change into our Redis load balancer causing internal traffic to be routed to an incorrect h
Disruption with some GitHub services
From Feb 2, 2026 17:13 UTC to Feb 2, 2026 17:36 UTC we experienced failures on ~0.02% of Git operations. While deploying an internal service, a misconfiguration caused a small subset of traffic to route to a service that was not ready. During the incident we observed the degradation and statused publicly.<br /><br />To mitigate the issue, traffic was redirected to healthy instances and we resumed normal operation.<br /><br />We are improving our monitoring and deployment processes in this area t
Some OpenAI models degraded in Copilot

Claude Opus 4.6 Fast not appearing for some Copilot users
On March 3, 2026, between 19:44 UTC and 21:05 UTC, some GitHub Copilot users reported that the Claude Opus 4.6 Fast model was no longer available in their IDE model selection. After investigation, we confirmed that this was caused by enterprise administrators adjusting their organization's model policies, which correctly removed the model for users in those organizations. No users outside the affected organizations lost access.<br /><br />We confirmed that the Copilot settings were functioning a
Incident with all GitHub services
On March 3, 2026, between 18:46 UTC and 20:09 UTC, GitHub experienced a period of degraded availability impacting GitHub.com, the GitHub API, GitHub Actions, Git operations, GitHub Copilot, and other dependent services. At the peak of the incident, GitHub.com request failures reached approximately 40%. During the same period, approximately 43% of GitHub API requests failed. Git operations over HTTP had an error rate of approximately 6%, while SSH was not impacted. GitHub Copilot requests had an
Delayed visibility of newly added issues on project boards
Between March 2, 21:42 UTC and March 3, 05:54 UTC project board updates, including adding new issues, PRs, and draft items to boards, were delayed from 30 minutes to over 2 hours, as a large backlog of messages accumulated in the Projects data denormalization pipeline.<br /><br />The incident was caused by an anomalously large event that required longer processing time than expected. Processing this message exceeded the Kafka consumer heartbeat timeout, triggering repeated consumer group rebalan
Incident with Pull Requests /pulls
On March 2nd, 2026, between 7:10 UTC and 22:04 UTC the pull requests service was degraded. Users navigating between tabs on the pull requests dashboard were met with 404 errors or blank pages.<br /><br />This was due to a configuration change deployed on February 27th at 11:03 PM UTC. We mitigated the incident by reverting the change.<br /><br />We’re working to improve monitoring for the page to automatically detect and alert us to routing failures.
Incident with Copilot agent sessions
On February 27, 2026, between 22:53 UTC and 23:46 UTC, the Copilot coding agent service experienced elevated errors and degraded functionality for agent sessions. Approximately 87% of attempts to start or interact with agent sessions encountered errors during this period.<br /><br />This was due to an expired authentication credential for an internal service component, which prevented Copilot agent session operations from completing successfully.<br /><br />We mitigated the incident by rotating
