Roughly two hours ago I couldn't get in for about 45 mintues. When I finally did, the initial load took FOREVER, but then everything was running fine once I was in. From browsing around a bit it seems to be an issue at the initial load of the game...could very well be lots of people trying to play being the weekend and the event nearing its end. My advice is to keep trying until you get in and then just leave it open.
