SpaceXAI apologized Thursday after an outage at its Memphis compute center disrupted Grok and unnamed “compute partners,” according to Engadget. The company said systems had been restored and were “functioning nominally,” but did not disclose what caused the incident. Engadget reports that Grok was down for three and a half hours beginning at 6:30AM PT, citing a company status page. The incident was labeled a “models outage” and apparently affected Grok on X as well as its Android and iOS apps. The company’s public apology was directed both at Grok users and at “impacted compute partners,” Engadget reported. That phrasing indicates the company said the interruption affected parties beyond Grok users, though the identities of the affected partners were not specified in the company statement cited by Engadget. Elon Musk said in a separate post that SpaceXAI was “taking corrective action to ensure this does not happen again,” according to Engadget. The available reports do not say what failed at the Memphis compute center or what specific corrective actions the company plans to take. The timing overlapped with problems at other AI platforms, but the relationship remains unconfirmed. Engadget reports that Anthropic’s Claude began seeing “elevated errors for multiple models” around 6:30AM PT, affecting Claude Mythos 5.1, Claude Fable 5.1, and Claude Opus 5, and that Anthropic marked the issue resolved by 9:16AM PT. OpenAI also reported elevated errors across ChatGPT and Codex early Thursday morning, according to Engadget. Users began reporting problems around 7:30AM PT on Downdetector, and OpenAI said the issue was resolved by 9:55AM PT. Engadget says OpenAI did not elaborate on the cause. Engadget notes that Anthropic and SpaceXAI signed a deal earlier this year for Anthropic to lease compute from Musk’s AI firm. But the article also says Anthropic has not said whether its Thursday issue was related to SpaceXAI’s data-center outage, and Anthropic and OpenAI did not immediately respond to requests for comment. Who benefits: Grok users benefit from the reported restoration of SpaceXAI systems. Users of the specifically identified Claude, ChatGPT and Codex services also saw those reported issues marked resolved. Who's exposed: Grok users were directly affected, according to Engadget. Unnamed compute partners may also have been affected, but the company has not publicly identified them in the provided reporting.
