Why can't you check it by yourself? Try it through a proxy outside your internet area (means europe based proxy if you are in the usa)
and check their api is online on bitcoinwisdom.

It seems they updated their frontend.
Get real guys, this kind of FUD is stupid and it will effect your own rational behaviour when it comes to trading.
Everytime you trap yourself in such nonsense you will lose money with your next trades - nothing will make you lose
more money as fear.
