The eriswiki is intended to provide reasonably complete user & operator documentation for the cobaltirc family, a loose affiliation of networked servers including blackcobalt irc and a collection of sponsored servers. Additionally, software projects hosted on eris.oppresses.us have project pages here.
Perhaps you're looking to get started on IRC?
…maybe you're already on IRC and you'd like to know how to register nicknames and channels?
…or maybe you're confused and want to know just what this IRC thing is about?
Mar 13 2014: We have added a new European server: menthe.oppresses.us (located in Amsterdam).
Feb 15 2014: The phoenix.xyloid.org server will be shutting down this week.
If you are using phoenix.xyloid.org explicitly, try irc.cobaltirc.org or choose another server.

cobaltirc is a loose affiliation of linked IRC servers, commonly referred to as a “network.”
Our focus is providing our users with simple, reliable, secure chat services for their projects and Web communities.
The primary components of our network are IRC services provided by blackcobalt and the oppresses.us namespace.
We are directly descendant from the previous IRC projects CNCNET and icerealm, applying over 16 years of IRC experience.
