For the time being, use:
eqnet.eqemulator.net
as your server name. (eqemulator.net or
www.eqemulator.net might work too)
The server that had been run by Rogean is currently down. For reasons unknown to me, the alias
irc.eqemulator.net only points to Rogean's server instead of round-robin between his and eqnet, so you won't get anywhere with that.
It's unknown to me why RogNet is down or whether it will be back up soon. In the meantime I will post a temporary announcement so everyone knows what to do.
