In March, GitHub experienced three significant incidents affecting several services, including Actions, due to issues like exceeding Int32 limits, database migration errors, and an authentication provider outage. On March 1, a high error rate was caused by check suite IDs exceeding Int32, affecting job queuing and search functionality; a code fix was deployed to address this, and audits of external libraries were conducted to prevent recurrence. The incident on March 12 resulted from a database index change leading to full table scans and service timeouts, prompting plans for better tooling and index inventory management. On March 15, an authentication provider outage hindered hosted job processing, which was resolved once the service was restored, leading to considerations for extending authentication token lifetimes. GitHub emphasizes its commitment to service reliability and continuous infrastructure and tooling investment to enhance user experience, as detailed on their engineering blog.
