Same with Bittrex.
"The last block update occurred 31 minutes ago."
sh.t!
Just sent a test tx to bittrex. It sees it unconfirmed, but "last block update occurred 55 minutes ago".
This is not good. They didn't update? Someone needs to contact them.
They were notified and should have been well aware of the hard fork. I have contacted them and let them know about the situation and asked them to update.
