http://www.broadbandreports.com/foru...2521~mode=flat & that's just the starting point! There's other articles involving both those companies if you wish to google for them. There may be some links for them on the forum. I know I read about Cox a month before I decided to comment about them. But I haven't been able to retrace the original article or 2 I read. Insight uses Sandvine! to filter & or block!
