is there a server up, is anyone playing?
Good news: 2 servers up, one for Arma 3 (216.105.171.156:2302) and one for Arma Reforger (147.124.197.80:2001). 8)
Bad news: Work has been kicking my ass since last April. Outside of the LAN party last summer I have not had the time or the energy necessary to maintain them. :-[ Fortunately, it looks like things are finally returning to a much saner pace.
I'm off for essentially the latter half of December. I'm looking forward to take some time fine tune both of them.
BTW, co-op options for Arma Reforger are improving quite a bit. In addition to the Game Master mode, there are any number of co-op missions in the Workshop. In addition, the latest release of AR has added a new albeit small island, a new official co-op mode, and what sounds like some pretty decent quality of life improvements to the editor. Hopefully those changes to the editor will make a lot easier to build and publish missions.
