They communicate that openly tho:

Regular maintenance window: We're meeting every Tuesday starting 18.00 Berlin time (currently 17.00 UTC), lasting up to 8 hours. While we announce large scheduled downtimes in advance, there might be minor interruptions due to maintenance work happening during the meeting. Please be patient in this case.

Not sure if that's also for the Pages feature, but in general having a weekly 8hr maintenance window is not optimal.
