It keeps happening and now its happening in the overworld. Error 90006.

As per my location, I am in an NA server but I am in one of the major Antilles to the southeast of Florida and our internet is connected to the NA side. However, my connection is just terrible. It got bad when they up and moved the servers but now, now its insulting. Heh, and the character information before login has the audacity to tell me it has an "excellent" connection.

Just what is going on?
