Prime Time - The time a singular player is awake and active, and anything that happens during this time is obviously a negative impact on his gameplay and thus, must be vocalized aloud in a very unappealing manner.

J/King. It is amusing no one actually does server maintence at different times depending on what cluster the server is currently hosting to ( area region. ) Then again, you'd have one region literally ahead of other regions in terms of server versions and updates and you'd have collissions if a player not from that region tries to play on a server that is not their region.

VERY tricky since EU and NA servers are both in Canada, unless they moved them and I didn't get the memo.
