So I feel like I need to address this specifically because there is an incredible amount of incorrect info being passed around, especially here.
No, the DNS server are both up and running. Request forwarding is disabled for non-sponsors, due to it being abused. You can read more info about the situation that caused open forwarding to be removed here. For non-sponsors connection tests will pass and will allow access to the exploit host that's running on the same server. You can also access resources directly by IP address.
