I just connected with no problems using irc.lunarnet.org
Additionally when I did connect I got this notice
15:57:43 -Global- [Logon News - Jul 27 2006] In case of problems, IPs: Eldrasia - 85.189.72.13, RPGCafe - 69.90.127.232, Obsidian - 70.72.131.243, Castleheck - 209.223.7.197
Maybe that'll help you.
