this is because status pages, at least the green/yellow/red light bits, are usually updated manually by a human. because if you automate those things, the automation can fail.
also, it's a weekend, a holiday weekend for some, so expecting updates to happen on the minute is a little unrealistic.
ALSO, it may take a bit of time for their "what is and is not really down" process a bit of time to be followed. on the weekend. by people who maybe haven't done this before outside of a training event 9 months ago or something.

it is not hard to imagine how, to me.
