"Maybe Available"
 

Both the website and the app, when I do a search for rooms in a city for specific dates, are returning lists of all the hotels in the city (as usual) but with only an indication that the hotel "maybe available" rather than with an indication of the rate (or of unavailability). I have to click on each hotel to see the prices for that hotel only. Having to click all of the hotels is really annoying.

I've never seen this before. Is anyone else having this problem?

This usually happens every Sunday morning.

As noted, this happens due to what I assume is scheduled maintenance of the database and/or computer systems at the central reservations level (as opposed to the individual hotel level). It's always in the dead of night (here in the United States).
