OK, that's one out of three. How about the other two?

Output from a smarter traceroute client like "mtr" would be helpful. See
below for usage. "mtr" is available for most non-braindead unixes, and
is pre-installed on many modern Linux variants.

Looks fine from here, on iiNet Western Australian ADSL2+ via local

Australia to Turkey via Sydney and the USA. I see similar results from
other hosts. Performance when accessing the server is fine. This sample
