@phoenix:[/home/ssahmed] traceroute cache01.tor.pathcom.com
traceroute to cache01.tor.pathcom.com (209.250.153.18), 30 hops max, 38 byte packets

Their tech support was either clueless or lying to me. Frankly, I
suspect the latter!!

Tried that. Didn't help. I converted the URIs in my
/etc/apt/sources.list to use ftp instead of http and things are better
now.

Its interesting that you talk about bandwidth reduction through this
transparent proxying mechanism. About 2 weeks ago, my ISP relocated
their data-center to a new location and upgraded their modem pool. They
said that all that would result in better performance for Pathway
customers. Since about 2 weeks, I have noticed a slight but consistent
reduction in their bandwidth. The best downloads that I can get now are
at about 3.1-3.3K/s. Prior to that I was getting about 4.1K/s
consistently.

Thanks for your helpful and informative posts Jason.
