What happened
On the morning of July 15, 2026, ChatGPT went down worldwide. Users could not log in, chat or make images. The cause was upstream connection errors. That means a failure in a service ChatGPT depends on. OpenAI's enterprise API and its Codex coding tool stayed up. Service returned the same day.
The context
