How we know
We request Claude's published status feed where one exists, and separately time a plain request to claude.ai. 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 Claude. Their official status page is the authority on cause and affected components.
