Kicked from dungeons 3 times from error 90000

As the title says I have been mid dungeon MID boss fight and randomly get the 90000 error. I know my connection is fine due to the fact I was watching a stream as I was playing and it didn't stutter for a second And I've been on ventrilo with no lag at all.

Every time this happens I then have to wait 45 mins of spamming log in to get back in.

I am so freaking pissed off it took me 3 runs to complete Stone Vigil.

Is anyone else having this problem?

Oh good now I can't even pull up the Na/EU server list. SE this is insane how can you be so unprepared and Did you not learn anything from every other mmo?

You need a window for DCed players to get a guaranteed spot back on, Why should I have to reque for a dungeon that i was so close to completing because you can't guarantee a stable server.
