crazy_bob has posted the following message on the official forum:
if you know someone having trouble accessing the board tell them to use: http://184.108.40.206/
It appears that the domain has been suspended, this means that it no longer directs you to our servers. A temporary fix would be to access the board using the ip address http://220.127.116.11 and hopefully kev will remove the redirection so eventually you CAN access the board temporarily via the IP address. Spread the word if you can still visit the site to people who can't but make sure they know that this ip address won't work just yet until the redirection is removed.
