Same here. I've had a lot of 503 errors on IOS but hardly ever on PC. Then, starting over the last 24 hours, I'm getting freezes, lags, and 503 errors all the time. Can't play the game for more than a minute or so before a freeze/error pops up and I have to reload the page, which sometimes takes several minutes. Happens in all areas - story, troll fights, pvp, market.
