There are several threads asking for SA servers back from February that got replied with basically denial, wether it was the server provider fault or the lack of players, the devs never gave a clear answer on why they couldn't get the south american community servers, the thing is we wont get servers during the early access and I bet my ass we won't get them in release either, and at this point were the NA servers are struggling with players we can just forget about it and look for another game to play. That is one of the reasons I left the game but whatever, I don't even care about multiplayer at all now
if you really want to play MP wait for the dedicated seevers
