Arena is only test server and will stay as pvp server. Now admin is preparing all servers (x5,x15,x30) for IL...ye...after 6 months :/ and arena will be wiped or dunno.
www_Dragon-community_net (use dots in _place) you can find everything here.
Servers are down for 1-3 days for update and they will work.
Id like to see new players on Infinity x5 ^^
