Just talked to a network engineer friend of mine at Time Warner who says it was a routing issue in their DC/NY Metro corridor. The network was "accessible" - but you couldn't get to any websites because it effectively took the DNS (Domain name servers) offline - which meant nothing would "lookup" correctly. (Think of calling Information and getting directed to the wrong phone number).
This not only affected Time Warner, but also their peer (connection) with GlobalExchange - a major nationwide carrier. Because of the depth of the issue, it's suspected that a routing table (called BGP) was corrupted and caused the issue. This could happen to anyone, fortunately, TW has the techs on staff and the resources (contacts) to get this resolved pretty quickly.
TW Phone and Internet run in the same physical spectrum of the "wire" - whereas cable tv operates at a different frequency (even digital tv). That's why phone and Internet were out, but not cable tv.
Overall outage was around 2 hours. It should be 100% resolved at this time.
