Yeah this has been happening to me,

I got suck at the Rhauban Cold Steel instance, so decided to go do other things. I was attempting to level RDM in PoTD, but as soon as you load in, you get kicked... then have to wait in the queue just to get back into the server, and if your character hasn't been kicked from the party yet for DC... you get through the queue and log back in... only to be kicked again... and at the back of the queue again trying to get in.

Its a vicious circle.
