I just received my three recent mtgox -> dwolla transfers. Additionally a mtgox employee has confirmed that mtgox is once again transferring money to dwolla:

"I've just been advised that Dwolla is now processing!"

"If your transaction did not get through, please send the reference number and indicate it's a dwolla transaction to support@mtgox.com - we'll look into it."
