Disruption with some GitHub services

Resolved

On April 17, 2026, between 14:46 UTC and 15:12 UTC, users experienced a degraded web experience on GitHub.com. During this time, approximately 1.5% of web requests resulted in errors, with some users encountering slow page loads or failed requests. The issue was caused by capacity saturation of a caching component in one of our data center regions. We mitigated the issue by redirecting traffic to an unaffected region and rolling back a recent deployment. The incident was fully resolved at 15:18 UTC. We are taking steps to provide appropriate capacity for this caching path to prevent recurrence.
