Well with so much negative who-ha over their testing of metered usage in Beaumont, TX, which some people take as gospel of what will happen nationwide, as posted on DSLReports, in some areas of NY state (CNY, STNY and NYC) Time Warner is testing PowerBoost technology that Comcast has been working on deploying nationwide for the past year or so. It as offically launched in parts of NYC though. PowerBoost takes a chunk of unused bandwidth on a node and lets you download large files at speeds above what you're provisioned for. Upwards of 30Mbps down. This will also create false inflated results on speed tests. Comcast does PowerBoost on both Up and Downstream, TW is down only currently. As you can see no PowerBoost here yet, but still great speeds.
