ChatGPT, Claude, and Grok Go Down Nearly Simultaneously
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.
Reporting from 1 source: GIGAZINE.
On the night of September 3, ChatGPT, Claude, and Grok all stopped responding within a short window. 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.
Anthropic staff member CJ Avilla posted that infrastructure issues caused partial outages across Claude Code, the API, and claude.ai. SpaceXAI reported that its problems traced to an outage at the Memphis compute center.
The two statements do not explain why the outages clustered. OpenAI and Anthropic have not issued official statements. One observer, Paris Marx, noted that for a brief moment, millions of people had to use their brains again.
