Several GPT models degraded
On July 25, 2026, between 09:07 and 10:04 UTC, the GPT-5.2, GPT-5.3-Codex, GPT-5.4, GPT-5.4 Mini, GPT-5.6 Sol, GPT-5.6 Terra and GPT-5.6 Luna models experienced degraded availability in GitHub Copilot products and IDE surfaces. Requests to these models had an average failure rate of 5.6%. Other Copilot models remained available as alternatives.<br /><br />The degradation was caused by an issue with an upstream model provider. Success rates returned to normal after the upstream issue was mitigate
Incident With Blocked GitHub.com Traffic
Between July 23, 2026 at 18:45 UTC and July 24, 2026 at 11:19 UTC, an abuse mitigation update caused some legitimate customers whose traffic was routed through our Central Europe and South America edge locations to be incorrectly blocked from GitHub.com. We estimate that approximately 0.25% of GitHub.com requests were affected during this period. This was caused by an abuse mitigation configuration that incorrectly classified legitimate traffic. We mitigated the incident by reverting the update
Latency issues across a number of services
On July 23, 2026, between 07:08 and 09:39 UTC, several services experienced delays: 8% of actions workflow runs experienced an average run start delay of 10 minutes, 5% of webhook deliveries exceeded SLO, and code scanning, repos, notifications, issues and pull requests experienced increased latency over the life of the incident. <br /><br />The root cause of the incident was a node of our background job processing system which did not recover after entering scheduled host maintenance. The i
Disruption with actions hosted runners
On July 22, 2026, between 19:36 UTC and 22:04 UTC, GitHub Actions experienced delayed and failed job starts on GitHub-hosted runners. The incident was caused by an unhealthy state in a backend data service responsible for provisioning hosted runners, preventing runner acquisition for a subset of workloads. During most of the incident, approximately 15% of workflow runs on hosted runners were delayed by more than 5 minutes, while roughly 1% failed to start.<br /><br />At 21:49 UTC, we restored th
Some SSH connections using deploy keys are failing
On July 21, 2026, between 07:41 UTC and 11:57 UTC, the SSH Authentication service was degraded and some SSH connections failed to authenticate. On average, 12.2% of SSH authentication requests failed, peaking at 15.7%. Both user RSA keys and deploy keys were impacted. This was due to a change in how our SSH service handled one public-key authentication method that caused the affected authentication attempts to be rejected as invalid. <br /><br />We mitigated the incident by reverting the change,
