Cablevision has released its 100 Mbps service in Long Island, NY termed Optimum Online Ultra. 100 Mbps is the download speed while upload speed is rated at 15 Mbps. While I agree with Om Malik that Cablevision is doing things differently than many other cable companies who are effectively fighting with customers by implementing broadband caps... A little known secret about Cablevision broadband is heavy users are effectively restricted to a penalty box which drastically reduces their upload and download speed until they upgrade their service level or call and have the service reset.
Still, I consider the company's broadband service to be among the best values in broadband access in the country and have nothing but praise for a company that not only provides broadband at $1/Mbps but throws in free WiFi to boot.
