As you can see here there is a congestion in the network https://blockchain.info/unconfirmed-transactions maybe someone is spamming the network, which is why even the transactions with the normal fees are taking too long to confirm, but it will ultimately subside and when it does, your transaction should go through.

Be safe and use a .0005 fee until we get a blocksize increase.

Thats one more proof that we urgently need to increase the blockzise.
Block are already full and ths kind of dealys are getting to be more common. This is bad because it causes a lot of issues between buyers and sellers.
It can even mine the trust in bitcoin on businesses as shops who are already accepting bitcon.

There has been, what seems to be a spam attack or unannounced stress test on the blockchain and as a result, the blocks have been filled with some tx's with virtually no fee's. This has caused problems for other people, who has paid normal fees.

You are just one of the unlucky people, who made a transaction during that traffic jam. This is just one more reason why the developers should act on this type of rubbish.
