Server is no longer being paid for.. Someone forgot to pay the bill.... I did not renew it yet simply because there was not a lot of interest with other games that came out. If people are interested in getting the server going again, I can.
Jim who has been playing with us recently has just rented an ARMA 3 server. Capable of handling 25 players. He is working out the details of running it now. Pointed him in your direction Gihz. He should be contacting you on steam.
