Grok went down about two hours before the other two. The reason the outages overlapped is not clear. During US business hours, chat interfaces and API services returned errors, disrupting companies that had just started their day. SpaceXAI attributed its problem to an outage at its Memphis compute center. Whether OpenAI and Anthropic share that facility is unconfirmed, and both companies have yet to issue official statements. Services were restored by the time the article was written.","whyItMatters":"The near-simultaneous failure of three rival AI services during US business hours shows how dependent daily work has become on these tools, and the unanswered question of shared infrastructure leaves the cause open.","webCardHtml":"\u003cp\u003eAnthropic staff member CJ Avilla posted that infrastructure issues caused partial outages across Claude Code, the API, and claude.ai.
