OpenAI and Anthropic Experience Outages on September 3

On Thursday morning, September 3, 2026, AI chatbots from Anthropic, OpenAI, and xAI experienced outages. SpaceX, the parent company of xAI, attributed the issues with its Grok service to an outage at its Memphis compute center. The outages coincided, leading to speculation about a shared third-party service provider, but OpenAI and Anthropic did not confirm any external source. SpaceX did not respond to requests for comment but apologized to its compute partners. OpenAI spokesperson Kathleen Chaykowski stated that a routing error starting at 7:43 am PT made ChatGPT and Codex unavailable for some users, with a solution implemented by 8:17 am PT. Anthropic reported a partial outage beginning at 6:23 am PT affecting its Claude models, resolving the issue by 9:16 am PT. xAI's Grok service reported outages starting at 6:30 am PT and marked the situation as resolved by 10:05 am PT. There were also unconfirmed reports of a possible Google Gemini outage, but Google did not provide a comment. Despite the simultaneous outages, OpenAI and Anthropic did not identify a shared cause, and major internet infrastructure providers reported no outages.
