That makes no sense at all. Those high packet losses on hops 3, 4, and 5
show that their network was screwed up at the time. I can (currently)
traceroute to 62.219.189.9 from California with 5% packet loss and the
packet loss was from my side (I am currently having DSL problems locally).

As for the "tech" that asked you to do an iptrace, don't worry about it,
your mtr should have been more than sufficient for them to realize that
*they* had a problem with *their* network.

BTW: Next time you use mtr, use the -r & -c <count> commands as shown
above and that will give you a printout that you can then copy & paste.
-r is for report and -c is for count. So in the above I set it to send
20 packets and at the end 'print' the report to the terminal.
