The server is up, but it seems there are some problems. Port 80 is alive, but not giving the common http answers. Given that a hungarian tested it and it seems to work, I assume there are some problems associated with connections from abroad. Doesn't work for me too. I hope Team Inferno's site to be back up soon for us non-hungarians, it's been very useful for me.
I'd like to spend a word for Team Inferno members too: I met just two of them online and they have been both very kind and helpful: one (Commander) sent me a setup when I asked for one to the people in the server, the other (Szabo) had my personal thanks to the whole team for their remarkable service. Awesome job, Team Inferno.
