One day april fool's joke:

> On April 1, 2018, as an April Fools' joke, the 1990s IRC server eris.Berkeley.EDU server was resurrected. Some EFnet admins worked with the Open Computing Facility student group at UC Berkeley for months to resurrect the server for April Fools. Only a very few EFnet staff were aware of the efforts and the server was linked in via a defunct H:line for the (normally) leaf (client-only) server irc.efnet.nl, bypassing the normal linking procedure. As of 12:30 UTC on April 01 2018, eris.Berkeley.EDU was once again a valid IRC server on the "Eris Free" IRC network and accepted clients.[11] At the same time, efnet.org begin redirecting to erisnet.org.[12] eris.Berkeley.EDU delinked on April 02 2018 at 19:50 UTC.

Knowing only the name Eris Free Net, and none of the history, this doesn't mean anything to me. I have no idea if this is a network that's free of Eris, or a free network named after Eris. While I have a vague memory of a server named Eris having existed in the past, I don't know if said server is the same Eris in the name, or a different Eris that may have a direct (ownership)/indirect (named in honor of)/no link with the server. Eris is the Greek goddess of discord and strife, not something you'd want in your community.
