Yeah like their page says "Scheduled Maintenance" which is total B.S. Talking to people at my university's IT side of things Canvas has said nothing to any clients.

The "scheduled maintenance" thing is likely just because that's the easiest maintenance page to throw up site wide, or at least it was back when I was on the Canvas deploy rotation back at Instructure ~10 years ago.

That doesn't excuse any of their other messaging though.
