We're seeing very poor performance on Cogent in Chicago to major sites 
such as CNN and Salon. Traceroutes indicate packets dropping inside 
Cogent's network and at their handoff to at atdn.net. Opened a ticket with 
Cogent around 10am Central, haven't heard from anybody since.

Not necessarily related to your problem, but maybe another data point.
