If you’re going to force us to use your sh**y servers to play cooperative, the least you could do, is ensure that they remain working during the one damned time of the year that many people have the time available to play. I don’t care that your support staff need down time too - they should be taking vacations when the player numbers are NOT at their highest. And how about the professionalism of an announcement?
