GitHub outage hits pull requests, issues, and API on May 27, 2026

GitHub reported an incident at 12:15:14 UTC on May 27, 2026, affecting pull requests, issues, Git operations, and API requests [GitHub Status]. The company has not disclosed the root cause or a resolution timeline, though the status page confirms ongoing impact across core development workflows.

Service degradation was logged across multiple systems, including repository management and API endpoints critical for automation and integrations [GitHub Status]. Engineers relying on GitHub Actions, webhooks, and third-party tools faced disruptions, though the extent of failed deployments or CI/CD pipeline failures has not been quantified.

This is not the first major GitHub outage; past incidents in 2022 and 2024 revealed vulnerabilities in its global infrastructure, particularly around database replication and edge routing. While GitHub has invested in redundancy since then, this event suggests persistent fragility in high-availability systems under real-world load.

The incident remains active as of the latest update, with no estimated time for full restoration. Users are advised to monitor the status page for patches or mitigation steps.
