Ask HN: Why were OpenAI, Claude, and Grok simultaneously down?
Points and comments are a snapshot, not live.
OpenAI, Claude, and Grok experienced simultaneous outages, sparking speculation about shared infrastructure or a broader issue.
ChatGPT, Claude, and Grok all went down around the same time, according to user reports on Hacker News. OpenAI's status page eventually listed a resolved incident, while Claude and Grok also showed irregularities. Users reported a global 404 error from ChatGPT's backend, with Cloudflare ray IDs pointing to various data centers. Speculation arose about a common cause, such as a SpaceX data center issue, Cloudflare problems, or the release of OpenAI's 'Astra' that day.
What commenters are saying
The dominant sentiment was a mix of panic, dark humor, and dependency anxiety. Users joked about being unable to work, with comments like "back to pen and paper" and "time to end the day here." Technical speculation centered on DNS, BGP, Cloudflare, and a potential shared data center provider like CoreWeave or SpaceX. A key observation: existing sessions continued working for some users, but new ones failed with a 404 error, suggesting a routing or quota issue rather than a total shutdown.
