I live in LA and just recently moved and practically my only internet option is TWC. However, FF is the only game I have problems with. I have played on east coast servers with other games such as CSS and TF2 and even Battlefield. Never had a problem having just over 100ms ping. But it's gotten so bad that being my main a PLD I can't get past T2 with the lag that I get. I have since given up on my group as it wasn't fair that I would miss a silence on ADS and we would wipe because of it. Personally I don't think it's TWC that is the problem.
The problem is SE and their logic to place the only data center for North America way the hell north east into montreal. I don't care if I had FiOS max speed of 300DL and around 75UL. I would still have lag simply because the server is so damn far away. The tracert is only half the issue.
FYI to either ping or tracert your server check out
www.arrstatus.com to get the correct IP for your server. Below is my tracert for Catcuar...im screwed for Coil.
