In terms of campus to provider. Humorously I say "We lack a significant amount of bridges between campus and the cable provider." More seriously, while their are a few bridges I can think in our area only one is remotely close to the path between cable provider and campus. The central CO for ATT(SBC) for our area is not in the same location or direction as the cable provider. Of course this is no guarantee of a different physical routing path but it does mean if paths cross or converge it does so much farther up the stream. In terms of provider level to level3. As you mentioned previously One Wilshire is likely the biggest single point of failure for services routing to and from the southern california area. ATT seems to also have significant investments of routing pathways in Ontario California and any major outage there seems to effect everyone east of the 55 freeway. Level3 has told us they don't go through the same conduit and On Oct 4, 2006, at 11:06 AM, Valdis Kletnieks wrote:

The Cable provider uses their own cabling and uplinks via Fiber to Level3 and MCI, so it does not intersect with our phone provider.Playing devil's advocate here - how do you *know* that your Cable fiber to Level3 doesn't go through the same conduit under the bridge as your telco's fiber to wherever they connect?
