How we know
We request ChatGPT's published status feed where one exists, and separately time a plain request to chatgpt.com. A state only changes after two consecutive readings agree, so the recorded window can be a few minutes wider than the true interruption.
This is an independent measurement and we are not affiliated with ChatGPT. Their official status page is the authority on cause and affected components.
