   On October 1, 2026, between 13:04 UTC and 13:34 UTC, users experienced two periods of slow page loads and intermittent request failures on GitHub.com. On average, the error rate was 0.52% and peaked at 6.13%. An unusually high volume of incoming traffic placed additional load on our traffic-handling infrastructure, delaying requests before they reached our application servers. Performance returned to normal as the traffic subsided, and we have since applied additional traffic filtering to protect against similar traffic. We are improving alerting for delays in our traffic-handling infrastructure and strengthening our automated traffic protections to reduce our time to detection and mitigation.

Impact, status and times are the vendor’s own, as last archived. View on stspg.io (opens in new tab).
