I just want to say... this is ridiculous (not you, the backlog). 0.002+ BTC fee on a somewhat small (byte-wise) transaction and after 7 hours it still has ZERO confirmations? Wow...
Looks like it was caused by a DoS vulnerability in bitcoin (see the reddit link above) but fortunately it appears that miners are no longer mining (?) the exploiting transactions, so the backlog has cleared up and it should be business as usual.
(I hope the miners have figured out how to identify and remove the exploiting transactions, rather than just the attacker has stopped)
