I used to use Road Runner. I switched to FIOS. Way faster and a lot cheaper, too.
I had 10mbs down and 1mbs up, but I have a server for small business so I needed more upload speed.
FIOS is giving me 15mbs up and down.
I know that Road Runner is fiber optic cable to the "node."
As I understand it each node distributes to from 200 to 300 modems. So all this heavy duty downloading is causing those 200 homes to get less download speed.
