Jeff MossWhen I worked at #ICANN years ago there were these great pictures of early networking and Internet typologies on the wall at the main office.
You could no longer get them from the publisher, so I took pictures! [1/2]:

@thedarktangent That 1984 Usenet map shows two nodes in Arizona, which geographically appear to be in Tucson and Sierra Vista (home of Fort Huachuca and a very successful city for Primenet, the first consumer ISP to reach it circa 1994-95), but the Tucson-located one appears to say "asu" followed by something I can't make out, which would put it in Tempe (metro Phoenix). Anybody know what the first two Arizona Usenet hosts were? ASU and UA? Or defense contractors in Tucson and Sierra Vista? (UA registered arizona.edu on January 23, 1986, over a year before ASU registered asu.edu (July 27, 1987).

@lippard @thedarktangent Check with Joel Snyder...he was undergrad at UA then.
@phil_stevens @thedarktangent Good suggestion, thanks!
@phil_stevens @thedarktangent Got the answer from Joel -- the two AZ nodes on that diagram are asuvax (Tempe, AZ) and noao (UA astronomy folks who run Kitt Peak and had their own IT infrastructure at that time). Joel thinks the UA CS department, which was ahead of ASU in networking at that time, was running NNTP over ARPANET, which it was already on at that time.
@lippard @thedarktangent Astronomy! Of course, I should have thought of that.
And of course Joel knew all the minutiae. He's good that way.
