Usenet feeds come from neighbors - it's a distributed flooding mesh.
UCSD's feeds are Stanford, who will probably shut down their USENET service in a short while, and CMU, whose status I don't know. You can get a feed from eternal-september.org, according to their web site, but I've never tried.
USENET is obsolete. Don't waste your time on it. - Brian
