GitHub suffered a Monday morning outage that disrupted core developer workflows, according to Engadget. The outlet reported that the developer platform had been down since around 9:40AM ET, with GitHub’s status page later listing problems across API requests, pull requests and webhooks. The outage also affected Copilot, Engadget reports, meaning developers using GitHub’s AI coding features may have seen service issues alongside the core repository and review tools. A Hacker News thread posted earlier in the morning also flagged pull-request access problems, with the submitter saying GitHub’s status page was still showing normal service at that moment. By shortly before 11AM ET, GitHub’s own status update reported roughly 20% error rates for web experiences and API traffic, according to Engadget. The same update said archive downloads and raw repository content downloads were seeing approximately 50% error rates. GitHub said it was applying mitigations based on its investigation and watching for improvement, Engadget reports. The cause had not been identified publicly at the time of that report. For engineering teams, the affected areas are not peripheral: pull requests sit at the center of code review, API requests underpin integrations, webhooks notify external systems, and raw or archive downloads are part of many repository workflows. The Copilot impact adds another layer for teams that have folded AI-assisted coding into their day-to-day development. Engadget also notes that this follows another recent outage affecting a Microsoft platform, after Xbox services were knocked offline for several hours late last month. The provided reports do not establish any shared cause between the incidents. Who benefits: There is no clear beneficiary from the provided reporting. Teams with local mirrors, offline build steps or alternative review paths may be less exposed during a platform outage. Who's exposed: Developers and operators relying on GitHub pull requests, APIs, webhooks, archive downloads, raw content downloads or Copilot are the most directly exposed. The reports do not quantify how many organizations or users were affected.
