now the mystery. where 108.220.213.121 is a publicly visible ip for the
server, a remote traceroute is wonky!!
consider the below traceroute, it reports hops up to 108.90.204.76,
stopping there instead of doing one more hop

could anyone shed some light on this mystery??
Your question and description are very confusing. Can you try again
with the details more organized?
What are you trying to traceroute to at the end? The route in the
traceroute doesn't match the "route" from earlier. I don't understand
what you think should be after that last hop.
ISPs don't always let traceroute requests go through depending on which
method you're using.
