Origin

Error 37 is a meme originating from Diablo III's release on 15 May 2012. The origin of the meme derives from an error message faced by most players when trying to login to the game. The error was caused by the overload of the battle.net login servers.

The error message reads "The Servers are Busy at this time. Please try again later. (Error 37)", as shown in the image below:

This error has caused misery to millions who have bought the game – because the login failure prevents the game from being played at all – not even for single player mode. The frustration of the Internet brought along the meme.

Memes

There are various types of this meme being created, mostly written from the viewpoints of various rage faces and other memes, where others are just used to humiliate Blizzard for allowing such a failure.
