In February, GitHub experienced a significant incident affecting the availability of its services such as GitHub.com, issues, pull requests, GitHub Actions, and GitHub Codespaces, due to a failed routine deployment that did not generate complete integrity hashes for Subresource Integrity. This failure resulted in the site serving 500 error pages to web users, although API and Git access were unaffected. The issue was swiftly resolved by rolling back to a previous deployment, and additional measures have since been implemented to enhance the robustness of the build process and prevent similar incidents. GitHub continues to provide monthly updates on service availability and improvements to its engineering systems to maintain service reliability, with further details accessible through their status page and engineering blog.
