GitHub Availability Report: July 2024

In July, GitHub faced several incidents causing service degradation, notably affecting Webhooks, GitHub Actions, and Copilot services. On July 5, a configuration change led to delayed Webhooks deliveries and GitHub Actions runs, which were resolved through service deployment and system updates. The Copilot service experienced significant disruption on July 13 due to mismanaged resource cleanup by a partner, which was addressed by rerouting traffic and collaborating with partners for future safeguards. On July 16, Copilot Chat faced near-total downtime due to routine maintenance issues, prompting improvements in reconnection logic. Lastly, on July 18, network issues in an upstream provider disrupted Actions workflows and Copilot services, which were mitigated by adjusting replication configurations and rerouting traffic. GitHub is committed to enhancing incident detection and recovery processes to minimize future impacts.
