The excess connection ban isn't for very long, only a few hours. Also note that the ban has only been set on your [email]user@host[/email] (a saving grace if you happen to be running multiple connections under the same [email]user@)[/email], so change your identd (/identd on <change>) to reconnect. The limit for [email]user@host[/email] connections on austnet is 3 (as you've just found out :P) and 4 from the same host if they all use a unique user@ (IIRC).
Hope that helps.
(just ignore the silly mailto: links..)
