GitHub Faces Frequent Service Failures Amid AI Coding Boom; Team Launches Infrastructure Overhaul

The AI coding boom and widespread adoption of agents have led to explosive growth in GitHub's user base, but also severe stability issues. Over the past months, GitHub has experienced multiple major failures and minor service interruptions, even sparking developer dissatisfaction—Ghostty, a well-known project, has decided to migrate to another platform.

To address these problems, GitHub's team is refactoring its underlying infrastructure, prioritizing service availability over new features. They've completed several optimizations, moved some computing power to Microsoft Azure, and isolated core services like Git and GitHub Actions. Additionally, they're building a multi-cloud architecture to enhance disaster recovery. Two recent failures (April 23 merge queue issue, April 27 search subsystem problem) have been disclosed, with the official apologizing and promising to improve communication mechanisms.
