What cascades to ChatGPT

ChatGPT is built on one provider. When one of these has an incident, ChatGPT often degrades too — frequently before its own status page admits it.

History is recorded from ChatGPT's official status plus our own independent checks. AIDownCheck is independent and not affiliated with OpenAI.
