Valindra's Tower bugged?

xhobosh

I usually run Valindra's Tower every day on at least one of my characters and every single time at least 2 or 3 people are disconnected at the start. Not quit but disconnected. I don't want to say every single time but it seems like it. Tonight it was everyone else in the party. I couldn't end the instance or quit without incurring a penalty. Bug? Or what?
