GitHub Suffers Major Outage Amid Surge in AI-Driven Coding Traffic

GitHub, the popular code hosting platform owned by Microsoft Corp., suffered a major outage on Monday that disrupted software development pipelines globally.

The hours-long incident was the latest in a string of reliability problems for GitHub, which serves over 180 million developers. The disruptions began around 9:40 a.m. EDT and initially manifested as performance degradation across core services.

Error rates spiked near 20% for web interface and API traffic, while archive and raw repository content downloads suffered a staggering 50% failure rate. Key capabilities, including GitHub Actions automated testing, webhooks, GitHub Pages, and the AI pair-programmer Copilot, were heavily compromised.

The service failure arrives amid growing developer fatigue over GitHub's operational stability. The platform recorded eight separate degradation incidents in July alone, followed by an Aug. 6 disruption that GitHub itself labeled 'unacceptable.'
