Poll has been locked. When its a temporary thing, please just ask on the forum rather than making a poll. If the server is whitelisted, you should get a message telling you it is whitelisted and that you are not on the whitelist. If it is not a whitelist problem, then you can feel free to get on irc to see whether anybody is in game. If people are only talking on irc and talking about how the server is down, then the server is down. If you see people talking in game, then you should check out this website:
