Ya, server's will be up on and off all week at random times that they'll announce. They're testing random stresses so there will be things like massive lag, or some feature disabled, etc. Not really getting to play the game at its finest.
There's that, and tbh I really need a break from that game and it's doubtful people will hop on to queue arena for an hour or so before they take the servers back down anyways, so there's really no point.
