Isn't there a new backbone in Spain, fed by mcvax?

I don't understand some of the map.  Like, why are ulysses, ubc-cs and
vucomp on there, all dead ends (and vucomp a restricted link at that)?
I submit that a 'backbone' link is to carry the news fast between
other backbone links, and I don't see these sites as doing that
(except for their leaf nodes ... hell, everybody does that). By the
same token, alberta would have to be looked at.

I can't decide what the rutgers-ukma link is.  Two paths?  Does the '+'
mean all the connected sites talk to each other?  Although it looks like
rutgers is the center of the Usenet universe, some links are triads
(rutgers/gatech/mcnc, rutgers/cmcl2/husc6, rutgers/ukma/gatech).
Since I assume this is all NNTP traffic, I wonder how much Internet
traffic would be cut by dropping some of those links, or making them
mostly unidirectional?

I also wonder about linus ... we're a hop away from husc6, and I don't
see much traffic through linus.

Are these maps generated by hand?
