Maybe think that this is a free 2 play server from a game which is something people do to have fun?
Yeah it went down for a few hours, so what? Ofi goes down every damn wednesday for hours. If it's down, go grab a beer with friends, go outside or even play another game.
And about compensation.. it can be fun to have a 2x weekend, but compensation for what? For playing on a free server? For being addicted to a game and not being able to withstand 8hs without it?
Instead of vita weekend I'd give out free shrink sessions
And if you really really really need to know what happened use google translate on the rus forum, sometimes there is some info there. Though for a crash at middnight, I'd say just go to bed or go outside
