World of Warcraft servers are experiencing Log-in Issues

The World of Warcraft servers are experiencing Log-in Issues at this time, at least in Europe.

When trying to log-in, players are greeted with the following screen with this error code: WOW51900102.

It seems that the servers are fine, but the log-in servers are having some issues. Be sure to stay in-game if you want to keep playing.

We logged out, which was a mistake.
