We have a few sites that regularly (hourly even) reset themselves.
During this time we have a nice page that displays links to other places.
However the message showing up indicates failure more than a regular event.
The message (when downtime is expected) should explain the downtime.
(perhaps not apologise? lol)
This issue is about tracking and changing all the ones that do go through a regular reset. i can think of the ones listed on moodle.org/demo
