my first thought was that the nick was lagged after the crash, but you said "the other night", which would be an awfully long time for lagged nick to still be there without pinging out. looking over their website, i see they can hide hostmasks, and they have nickserv. You could try ghosting it, /nickserv RECOVER Nickname NicknamePassword
followed by release command, /nickserv RELEASE Nickname NicknamePassword ( read details on their website at

Best bet is to ask in that network's help channel, #irc-help or post on their IRC forum.
EDIT: if by "killed" you mean you were klined, per their website: "For information regarding k-lines, please e-mail
kline@stratics.com - PLEASE NOTE: Only the party that is k-lined will receive information regarding their k-line. If you e-mail us for your buddy who was removed from the network, we will not discuss it with you. "
Its always best when you have a network specific problem to take a few minutes and look thru their website. i found it in about 3 seconds with google
