Dataforge is an fledgling independent, hybrid shell provider/tilde server operated by Wesley Banderia (aka; praetor) of Fort Worth, Texas. While it's core mission is to provide services to retrocomputing enthusiasts, it serves as a home for anyone. Dataforge is hosted on a fleet of Silicon Graphics machines, its primary tilde host is running on an SGI Challenge S. Dataforge UUCP, however, is running on a Google Cloud VPS for purposes of reliability and fault tolerance.
Eternal September is a free online Usenet feed for people who still feel the need to read net.news. You can only access text newsgroups (i.e. no alt.binary.*) and you have to register an account, but other than that it's open season. They also support UUCP if you roll that way.
