We had a little excitement on Wednesday, but not much is being said other than exactly where to cut the cable to do this. My question is, after looking at the chart, T-W's architecture is on the lower right, what was cut, a ring?

Here is a myth from T-W which is not a myth, it seems:

Myth 5 HFC cable services are less reliable than the data services of a telephone company.

Fact: Time Warner Cable's HFC cable services run over a ring-in-ring redundant network. The ring architecture provides multiple paths to each of Time Warner Cable's HFC nodes serving 1,000 or fewer customers. Should even one of the fibers to that node break, user traffic can continue to flow uninterrupted across another redundant fiber path. As such, the self-healing ring-in-ring distribution offers the user a continuous, secure connection to the Internet.

. . . now read this story from Wednesday (one truck did this):

Cable, Phone, Internet Service Restored to Thousands

Posted: Dec. 21 11:51 a.m. Updated: Dec. 21 5:40 p.m.

Raleigh - As many as 250,000 Time Warner Cable customers in the Triangle area lost their service for almost four hours Thursday after a dump truck knocked out a major cable, officials said.

Time Warner spokesman Tom Lawrence said a fiber-optic cable on Glenwood Avenue was cut at about 10:45 a.m. and restored at 2:15 p.m.

A dump truck drove under the cable that crossed Glenwood near Brownleigh Road, and the tarp-rolling mechanism designed to keep debris from flying out snagged a cable with 144 fiber-optic lines, Lawrence said. The cable wasn't severed but was pulled loose from a connector box, he said.

Television, digital phone and Road Runner Internet service were affected in Raleigh, Cary, Wilson, Goldsboro, Farmville and patr of Pitt County, Lawrence said. Service in Durham, Chapel Hill and Moore County wasn't affected by the outage, he said.

About 70 percent of Time Warner's Road Runner customers and about 60 percent of its digital phone customers were affected, he said. They either lost service entirely or experienced slow Internet connections or "degraded quality" on their phone calls, he said.

Cable television service was affected on some channels in some areas, Lawrence said.

The CED Magazine reference states:

"The Cox Communications ?Ring-in-Ring? fiber architecture is an integration of a ?dedicated? fiber ring and a ?loop-through? fiber ring in the same fiber cable sheath [..............]"

Too bad the rings are in the same cable.
