I'm with TWC too. In the past when I've had R0 problems and it wasn't my modem crapping out (just swapped out again last week) or someone stealing cable at the neighborhood drop--it's been a routing stall in Virginia or Nova Scotia areas. Run some traceroutes to find your "black hole" and forward the log to your ISP so they can get someome to power cycle or something...lol.

Last time it was a big issue it was something RR had no control over (wound up being a Verizon FiOS segment going down), so the changed my config to shoot me through Charlotte, NC instead and put me on a different routing path and I was able to get through. Made things a little more laggy, but it allowed me to get back in the game.
