Copilot degraded shortly after, with error rates around 20% for web and API traffic and roughly 50% for archive downloads and raw content. Authentication systems including SAML, OIDC, SCIM, and Team Sync were impacted, though Git Operations, Packages, Pages, and Codespaces remained functional. No root cause was confirmed, though the incident follows reports of Azure infrastructure struggling to handle GitHub's traffic growth during an ongoing migration, prompting Microsoft to lean on AWS for support. ## Content On August 17, 2026, GitHub went down. Not a partial hiccup — a real, hours-long mess that took out the tools developers touch dozens of times a day. ## Timeline GitHub first flagged performance problems at 13:40 UTC (9:40 AM EDT), when it started investigating issues across its services. It didn't stay contained for long. Within the hour, the trouble had spread into API requests, Actions, Webhooks, Issues, and Pull Requests — basically the core loop of how people use GitHub every day. By 14:31 UTC (10:31 AM EDT), GitHub confirmed Copilot was degraded too, dragging the AI assistant into the outage alongside everything else. According to GitHub's status page, error rates hit around 20% across web and API traffic. Archive downloads and raw repository content fared worse, with error rates near 50%. Authentication also took a hit — SAML, OIDC, SCIM, and Team Sync were all affected, which meant even people trying to just log in were having a bad time. Git Operations, Packages, Pages, and Codespaces reportedly kept working throughout. GitHub identified the problematic component by early afternoon and reported signs of recovery, but the fix wasn't clean. After initial repairs around 16:36 UTC, Git Operations and API requests degraded again. Authentication issues, including for Copilot, stuck around until GitHub partially disabled authentication-token retries. The incident was fully resolved at 21:15 UTC — just under eight hours after it started. ## What caused it GitHub hasn't said. No root cause has been published, and the company has only said its investigation is ongoing. There's speculation tied to Microsoft's infrastructure situation — reports suggest Microsoft has been leaning on AWS to help absorb GitHub's traffic growth after Azure struggled to keep up with the platform's expansion during an infrastructure migration. Whether that's actually connected to this outage is unconfirmed. ## The reaction Developers noticed, obviously — an eight-hour outage touching Actions, PRs, and Copilot isn't something you can quietly work around. Some people leaned into the moment with jokes ( ## Questions this post answers ### What GitHub services were affected during the August 17, 2026 outage? API requests, Actions, Webhooks, Issues, Pull Requests, Copilot, and authentication systems (SAML, OIDC, SCIM, Team Sync) were degraded. Web and API error rates hit around 20%, while archive downloads and raw repository content saw error rates near 50%. Git Operations, Packages, Pages, and Codespaces reportedly kept working throughout the incident. _Teams tracking GitHub reliability incidents can follow outage breakdowns like this on daily.dev._ ### How long did the GitHub and Copilot outage on August 17, 2026 last? The incident lasted just under eight hours, from initial performance problems flagged at 13:40 UTC to full resolution at 21:15 UTC. A partial fix applied around 16:36 UTC caused Git Operations and API requests to degrade again, and authentication problems persisted until GitHub partially disabled authentication-token retries. _Developers planning around platform reliability can check incident timelines like this via daily.dev._ ### What caused the August 17, 2026 GitHub outage? No root cause has been published, and GitHub says its investigation is ongoing. Speculation points to Microsoft leaning on AWS to help absorb GitHub's traffic growth after Azure struggled during an infrastructure migration, but that connection to this specific incident remains unconfirmed. _Anyone weighing platform dependency risk can keep an eye on GitHub infrastructure reporting through daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@fabianletsch** · 8 upvotes > Roses are red > > Violets are blue > > GitHub is down > > But that ain't new **@zx8086** · 5 upvotes > No Pilot **@taiwofrancis** · 1 upvotes > Everyone jokes about outages until the CI pipeline stops running. 😂 **@vineyrawat** · 0 upvotes > Lately p0rnhub is more reliable than github **@bozzified** · 0 upvotes > it was total collapse this morning.. and they said, LLMs will make things better.
