Thanks.  What concerned me was the first hop...22ms. is ~ the distance
from Maui to Oahu, but why the Chinese IP?  Cruel joke?
I"m using Hawaiian Telcom's ADSL service and that first hop has always
been their gateway IP address.
Another TCP trace shows the first hop as 123.74.62.128...another CN
address.


I'm assuming your provider's network engineers (stupidly) assumed
123.x.x.x was a good idea for use in a private setup because it hadn't
been assigned from the global pool (yet).

Wouldn't be the first provider or service to not use proper RFC assigned
private IP space for their internal networking setup.

Well, in the 7-8 years I've been with them, they've never used Private IP space.
