I had a bit of trouble queueing for O4N just 20 mins ago or so. Despite me having completed it with both people I was partied with before and everyone double checking they hadn't unequipped a piece of gear and dropped themselves below the ilvl requirement it just wouldn't pop for us.

We went as a tank, a healer and a DPS - that queue should have been instant but we waited around 7 minutes.

I know it doesn't relate directly to your issue but I just think DF in general was having some issues tonight.
