GitHub is investigating degraded performance across several core platform services. The incident, first reported at 12:10 UTC on May 27, 2026, affects Git operations, Issues, Pull Requests, and API requests. Engineers continue working to resolve the issue, with updates posted to the company's status page.

The timing couldn't be worse for development teams worldwide. GitHub serves as the backbone for countless software projects, and any disruption to these fundamental tools immediately impacts developer productivity. Git operations are the lifeblood of version control workflows, while Issues and Pull Requests drive collaboration across distributed teams.

API request slowdowns compound the problem by breaking integrations that many organizations rely on for continuous integration pipelines, automated testing, and deployment workflows. Third-party tools that connect to GitHub's API are experiencing timeouts or failures, creating a ripple effect throughout development ecosystems.

Developers are advised to monitor the status page for real-time updates while postponing non-critical Git operations and API-dependent tasks until service restoration.
