In January, GitHub experienced two incidents affecting service performance and git users. The first incident occurred on January 30 at 21:48 UTC, lasting 35 minutes, and involved degraded performance for GitHub Packages and Pages due to a backend change, which was mitigated by reverting the change. The second incident on January 30 at 18:35 UTC lasted seven hours and involved an upgrade to the production Git binary, which included an internal gzip implementation that caused checksum mismatches for "Download Source" links, despite no content alteration. This was resolved by reverting the compression change. Both incidents are still under investigation, with more detailed updates promised in the next month's report, and real-time updates available on GitHub's status page.
