In May, GitHub experienced two significant incidents impacting the availability of its services, including API requests, GitHub Pages, GitHub Actions, and the GitHub Packages Container registry service. The first incident on May 8 was caused by failures in a MySQL database, leading to timeouts in the Container registry service, which was resolved by failing over to a database replica and implementing measures to reduce future impacts. The second incident on May 16 was due to a foreign key overflow exceeding max INT32, affecting GitHub Actions and Pages, which was mitigated through a schema migration to INT64 and removal of invalid token records. To prevent such issues in the future, GitHub is enhancing its internal documentation, alerting systems, and tooling, while also auditing INT32 columns and improving automation to avoid database inconsistencies and unauthorized access.
