Nobody Is Saying Why OpenAI and Anthropic Had Outages Today
OpenAI, Anthropic, and xAI chatbots suffered brief simultaneous outages; OpenAI cited a routing error and SpaceX a Memphis compute center outage.
ChatGPT and Codex were unavailable to some users from about 7:43 to 8:17 am PT Thursday due to a routing error, per OpenAI. Anthropic reported a partial outage with elevated errors on Claude Mythos 5.1, Claude Fable 5.1, and Claude Opus 5, resolved by 9:16 am PT, while declining to explain the cause. xAI attributed the Grok outage starting 6:30 am PT to an outage at SpaceX's Memphis compute center; no shared third-party infrastructure cause was confirmed despite Cloudflare, AWS, and Azure reporting no issues.

- Anthropic reported elevated errors on three Claude models but would not explain the cause
- SpaceX said Grok's outage stemmed from its Memphis compute center
