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 
802.11g . That latency is about what I expect for traffic from Western 
Australia to Turkey via Sydney and the USA. I see similar results from 
other hosts. Performance when accessing the server is fine. This sample
