I think a lot of states have (if not active, legacy) Internet backbones where schools and such had connectivity back in the day before the "general public".
Oklahoma's is "OneNet"[1], and we had a T1 at usao.edu back in '93 [2].
[2] I set up the very first USAO web site as a summer Independent Study project in '95, running a web server on our VAX 4700. People told me "You have to have a Sun box to run a web server!" and I proved them wrong. It was a fun 9-week gig, because the actual work only took me a couple of weeks, including creating a HTML version of the Student Handbook. Bits of the site I created persisted for almost a decade.
