Seems to be up for me. Try the actual ip: 188.165.205.86:27015.

If you want admin just post your Steam ID here (status in console) and we'll get that sorted out .

EDIT: Oh I see, server doesn't load when you join. Have restarted and all is good now.

EDIT2: I believe this was because someone changed it to a wrong map. Have corrected the maps you can change the servers to.
