High Ping and High Latency issues from Alexandria, VA

I have been experiencing both High Ping (> 130ms - > 250ms) and high latency from several online games based in California. I have also been getting ping results of > 100ms to Ashburn, VA which is less than 50 miles away which results in poor connection issues with VOIP applications.

Pingtest.net reports a connection quality of B and C based on the Ping and the Jitter even though I am currently using a top tier Cable Modem (3.0) and routinely test over 100 mbs on speed tests. Unfortunately, speed is only half of a quality network.
