In April, GitHub.com experienced three significant service interruptions, resulting in 5 hours and 36 minutes of degraded services due to various misconfigurations affecting internal routing, database connections, and networking switches. The first incident was caused by a misconfigured software load balancer, the second by database connection issues during data partitioning efforts, and the third by an erroneous networking configuration that propagated excessive routes. These disruptions highlighted gaps between staging and production environments, prompting GitHub to enhance its engineering processes by building a network staging environment for continuous integration and focusing on comprehensive software coverage. GitHub is committed to improving reliability and has pledged to address these issues to maintain user trust.
