That's pretty lame compared to your ipv4 results, but the length of
the path looks the same... puzzling... How much further (or less far)
is rich's box (traceroute6 -n netperf6.richb-hanover.com) on ipv6 vs
ipv4 (traceroute -n )

I have certainly seen bottlenecks, excessive delay, and packet loss on
he's gateways.

An "mtr" might be revealing during the test for spotting packet loss
further on the path.
