Primary:

irc.ferazelhosting.net

#prpg

Backup:

irc2.ferazelhosting.net

#prpg

Online IRC client, in case your client malfunctions: https://kiwiirc.com/client

Note that you will have to click "Server and network" and set it to irc.ferazelhosting.net, port 6667.

Another one suggested by swicked: https://client00.chat.mibbit.com/?url=irc://irc.ferazelhosting.net:6667/%23prpg

Note that you should probably only enter the primary into your irc client, as the two servers are not linked.

It is recommended not to use the names fatcat.ferazelhosting.net and nimnul.ferazelhosting.net (for the ferazelhosting.net servers in New Jersey and Kantō respectively) for IRC.
