Besides ensuring the minimal amount of player disruption it also ensures that the servers don't get bum rushed the second they finish and bring them back online which normally results in strings of login errors and potentially follow up maintenance for a crashed server.
Requoted, because everyone else doesn't seem to read the rest of the comments now.

It's emergency maintenance for hotfixes. It's written on the maintenance notice.
