In April, GitHub faced two significant incidents affecting the availability of its services, particularly the GitHub Packages Container registry and API requests. The first incident on April 1, lasting one hour and 34 minutes, was due to DNS resolution failures, impacting beta users' ability to manage container images. GitHub plans to increase DNS resolution cache times to mitigate future issues. The second incident on April 22, lasting 53 minutes, involved a bug from a recent data migration that disrupted repository creation due to an unexpected dependency on secret scanning. GitHub addressed this by rolling back the migration, updating their migration process, and removing the dependency in the application code. The company is committed to improving service reliability and encourages readers to follow updates on their engineering blog.
