GitHub suffered a widespread outage on Monday, August 17, 2026, disrupting developers who rely on the Microsoft-owned platform for code hosting, reviews, automation, and AI-assisted coding.<\/p>\n\n\n\n
The incident began at 13:40 UTC, when GitHub said it was investigating reports of impacted performance across some services. The company later confirmed that the issue affected Git Operations, Webhooks, API Requests, Issues, Pull Requests, Actions, Pages, and Copilot.<\/p>\n\n\n\n
The outage affected several parts of the software development workflow at once.<\/p>\n\n\n\n
Developers use GitHub to push code, review pull requests, track issues, run automated workflows through GitHub Actions, publish pages, and access GitHub Copilot. When these services slow down or fail, teams can lose access to key parts of their daily work.<\/p>\n\n\n\n
GeekWire reported that the outage disrupted software development work around the world and affected GitHub\u2019s website, code review tools, automated systems, and Copilot.<\/p>\n\n\n\n
During the incident, GitHub said it was seeing about a 20% error rate for web experiences and API traffic.<\/p>\n\n\n\n
The company also reported an approximate 50% error rate for archive downloads and raw repository content downloads. Other affected areas included SAML and OIDC authentication, SCIM, and Team Sync.<\/p>\n\n\n\n
GitHub later said it had identified the problematic component and taken corrective actions. The company reported signs of recovery, though error rates remained slightly elevated while engineers continued working on full restoration.<\/p>\n\n\n\n
GitHub Copilot was among the affected services.<\/p>\n\n\n\n
The status page showed Copilot experiencing degraded availability during the incident. Later updates said GitHub was still investigating sporadic Copilot authentication failures in some applications, while Copilot usage through the GitHub CLI and GitHub App remained unaffected.<\/p>\n\n\n\n
This made the outage more visible for developers who now use AI coding tools as part of their normal workflow.<\/p>\n\n\n\n
GitHub marked the incident as resolved at 21:15 UTC on August 17.<\/p>\n\n\n\n
The company thanked users for their patience and said it would share a detailed root cause analysis once available. As of the status update, GitHub had not yet published the full technical explanation for what caused the outage.<\/p>\n\n\n\n
GeekWire reported that the outage lasted about seven and a half hours from the first reported issue to full resolution.<\/p>\n\n\n\n
The outage adds to a challenging period for GitHub as software development increasingly depends on AI tools and automated workflows.<\/p>\n\n\n\n
GeekWire noted that GitHub has been dealing with months of pressure from AI-driven coding demand. The report cited earlier comments from GitHub CTO Vladimir Fedorov about the company needing to build for far more capacity as AI coding workloads grow.<\/p>\n\n\n\n
The timing matters because GitHub is no longer only a code repository. For many teams, it is also a CI\/CD platform, project tracker, package workflow, documentation host, and AI coding assistant.<\/p>\n\n\n\n
GitHub says all systems are now operational, but users are still waiting for the company\u2019s full root cause analysis.<\/p>\n\n\n\n
For developers and businesses, the incident is a reminder that even widely used cloud platforms can face major disruptions. It also shows how deeply GitHub is now tied to everyday software work, from pull requests and Actions to Copilot and authentication.<\/p>\n\n\n\n
