remember the "diameter of the internet"?

i sit behind cox-cable service at home, and in troubleshooting why my 
connectivity is *so* horrible, i find the following traceroute.  does 
anyone do any sane routing anymore?  does diameter matter (we used to talk 
about it a long, long while ago).  i guess i'm just old and crusty but this 
seems to violate so many natural laws.

i find in more random testing that i seem to be a minimum of 15 hops from 
anything, and it's not just the # of hops, it's the *paths* i travel. 
bouncing between two cities several times, on several different provider 
networks, from one border to the other.

wow.
