it's up right now, and since you said you've been trying for months, i would guess that you have some local issues.
are you using the default windows terminal program?
if so, step one is to get something half decent, you may wish to do a google search for (operating system) mud client
(like windows mud client)
many of us use zmud, or portal, or mushclient
step two is to see if you are behind a router, another computer, or firewall. - if so, post here with details
disabling all other running software is a good way to troubleshoot.
then, try this address-
host:
http://www.dark-legacy.com
port: 9898
you may also try
host: 64.124.186.158
port: 9898
