GitHub outage caused by traffic surge and autoscaling flaws

THE article discusses a critical incident involving a significant outage at GitHub, triggered by heavy external traffic and internal infrastructure flaws. Key points include the failure of autoscaling policies leading to network congestion, the automatic retries of requests causing a ‘retry storm’, and the longer recovery time of GitHub Copilot service due to abnormal request surges. Additionally, large-scale automated crawler traffic further strained the infrastructure during recovery. GitHub plans to revise autoscaling policies and review retry behaviors to prevent similar future incidents.
