Elder scrolls was a game of the year game they knew it would be big they should have been better prepared I can't even log into the game I paid $65 and not to mention the Xbox membership fee so I can actually play online...
Thats exactly the case. A large portion of EU players are going to NA server instead. Overloading the megaservers causing a DoS attack style issue. Thats my guess
