Was queued for Dun Scaith, after 40 minutes pops then someone withdraws, bugged?

Was queued for Dun Scaith (on that portion of Void Ark quest), and after 40 minutes of waiting queue pops and someone withdraws. No problem I think, it will pop again in a few minutes.

Then I look at the queue and all the healers & tanks are no longer in it and it's down to 6 DPS. Currently at over an hour wait.

It's no problem b/c I'm doing crafting quests anyways, but just curious if there's a chance it could be bugged or if eventually it will fill back up?

Edit: And as I posted this I got a pop. Go figure :/
