the comcast network is built out to keep your traffic on their network until it needs to peer out. which means you won't have to go directly out to the Internet after you request the page. you can stay on the comcast network all the way to FL if you are requesting a website there before you "touch" the internet.
its part of their own network called CRAN/B>. Also you'll have PowerBoost too
CRAN... I can tracert all the way to New Jersey and never leave Comcast's network!
