Although not totally unexpected, the much anticipated launch of Blizzard Entertainment's Diablo III had some setbacks as the servers were overloaded at launch time. Players trying to login were greeted with a "The servers are busy at this time. Please try again later. (Error 37)" message.
An official 'blue' post from the Diablo III website said "Due to high concurrency the login servers are currently at full capacity. This may cause delays in the login process, account pages and web services.
We apologise for any inconvenience this may cause and thank you for your patience while this is being resolved. "
