Thank you for reporting the gateway issue. We shall see what the problem is.
Also unfortunately today some of you may have noticed a downtime, we do have technical issues with our connection for the real server, it's unavailable for the time being.
We are working on it and shall report here when the problems are resolved.

A hijack attempt seems to be in progress. The .onion address is hard to reach (DoS?) while the gate.bitcoinfog.com clearnet site propagates a phishing page, terminated in phc6.onion (I don't want to propagate the full address).
It seems the hackers have compromised bitcoinfog's own clearnet DNS and are controlling the gate.bitcoinfog.com address, at least.
