I collected a little over 50,800 news paths from May 31 until now,
and, with some help from Gnu Emacs picture-mode and a perl program,
here is a map showing all connections that appear in 500 or more
articles. I managed to complete all the lines except the one from
uwvax to husc6, hence the (HUSC6) at the top.
Backbone sites are shown in capital letters. If someone else in the
Bay Area were to make this map, it would look almost the same except
for sites epimass, csi, and nsc, which only have a relatively local
effect. It was hard to draw "ames"; 16 different sites are shown
connected to it, making it the busiest mixing bowl for news.
It's also interesting to discover that almost all news from Europe
reaches the Bay Area via the path
mcvax!uunet!seismo!sundc!pitstop!sun!decwrl
which is not what one would expect from Spaf's map.
