GitHub Availability Report: December 2022

In December, GitHub experienced no performance issues, but a report details an incident in November that affected GitHub Packages and GitHub Pages. On November 25, an alert was triggered due to an outage impacting GitHub Packages, causing unavailability of container, npm, and NuGet registries, while RubyGems and Maven registries remained functional. This outage also disrupted GitHub Pages, leading to CI build failures and timeouts on repository landing pages. The issue stemmed from a third-party database provider's regional outage, which was mitigated before GitHub could execute a failover. Recovery ensued as the provider addressed the problem, prompting GitHub to consider enhancing resilience and automating failovers for future incidents. For ongoing updates, GitHub directs users to their status page and engineering blog.
