I used their service often and without problems but yesterday was the first issue with them.
Can I hope thats a delay because their ddos attacks?
Which Mixing services you can recommend?
I haven't used that bitcoinfog but I heard bad news in the past for this (underground) website, were the stolen bitcoin from bter exchange send there? Few bitcoin mixing services that recently are still working are bitmixer and cryptomixer, both of them are good and still working, but first try to solve this issue with bitcoinfog, if the blockchain says that it is confirmed then its bitcoinfog responsibility to credit your account/address.
