Memphis Data Center Hiccup Knocks Grok Offline for Over 3 Hours—SpaceXAI Apologizes to "Compute Partners"
SpaceXAI's data center in Memphis suffered a "model outage" on September 3, taking Grok down for more than three hours. The company also issued an apology to unnamed "compute partners." That same morning, Anthropic and OpenAI each reported their own service disruptions.
A single apology tweet has raised questions that go well beyond Grok's three-and-a-half-hour outage.
SpaceXAI posted on X on September 3, apologizing for the AI chatbot Grok's malfunction that morning—specifically noting it also wanted "to apologize to the compute partners affected." According to the company's status page, the incident, flagged as a "models outage," began at 6:30 AM Pacific Time and lasted three and a half hours, impacting Grok on X, as well as its Android and iOS apps. SpaceXAI did not disclose what exactly went wrong at the Memphis facility. Musk only stated in his own post that the company was "taking corrective action to ensure it doesn't happen again."
SpaceXAI never named who these "compute partners" are—but the timing raises eyebrows.
Around the same time—6:30 AM on September 3—Anthropic's Claude also ran into trouble. The company's status page noted "elevated error rates" across multiple models, including Claude Mythos 5.1, Claude Fable 5.1, and Claude Opus 5, with the issue marked resolved at 9:16 AM. Anthropic didn't say whether this outage was linked to SpaceXAI's data center—but notably, the two companies signed a deal earlier this year under which Anthropic leases compute from Musk's AI company. That partnership makes the timing overlap between the Memphis outage and Claude's downtime look less like coincidence and more like a real connection.
OpenAI, meanwhile, tells a separate story. Both ChatGPT and Codex also experienced "elevated error rates" that same morning of September 3. Downdetector reports show users started hitting issues around 7:30 AM, with OpenAI confirming the problem was resolved by 9:55 AM—again, without explaining the cause. There's no known compute-leasing relationship between OpenAI and SpaceXAI, so for now, the timing overlap looks like pure coincidence.
Three companies, three separate timelines, all converging on the same morning. SpaceXAI's apology to its "compute partners" has, for the first time, given outsiders a glimpse that Grok's underlying infrastructure may ripple far beyond its own product.
