Hmm. A traceroute from my home network (not involving AMPRNet)
from San Diego to the main NL gateway 213.222.29.194 gives a
fairly clean 15 hop path with less than 200 ms delay.

A traceroute from UCSD to the same gateway gets some very strange
routing:

and in fact never resolves.
A traceroute to 213.222.29.194 from a data center in Texas
shows some confusion inside a network 134.222.48.x, which
appears to be titled 'eurorings', and a further several hops
inside xs4all.net:

My first impression is that something is not quite right
on the other side of the Atlantic.
