I've been on TWC RR for about 5 years as well. Never had a problem (except setting up e-mail in ye old outlook for my dad, but that's nothing the excellent tech support couldn't answer!
) Speeds are usually excellent, consistent, reliable. Downtime is, and has always been due to user error. Just wish I could get a good cable signal in my room (modem's in here, everytime I try to split the signal both TV and bandwith go to shit.)
