Nope--just pointing out that Yahoo content is not stuck on the congested pathway in the direction in which the congestion exists, at least until Comcast decides to start sending sufficient outbound traffic to cause congestion in both directions. Just didn't like the portrayal of our connectivity as being stuck behind a traffic jam of other data, potentially causing Comcast users to subconsciously avoid going to Yahoo sites for fear they might be somehow affected by that line of cars. -- TTFN, patrick P.S.

Unfortunately Netflix's state of mind if you will is something we can't derive from the routing tables. They might have gone into this hand in hand with Level 3, wanting to make a point to Comcast/The FCC/The Public about something. On the other hand, Level 3 might have told them things were just peachy with Comcast and they could easily handle this traffic and Netflix got sold a pig in a poke. If so, they could be rather unhappy that their new CDN partner is dragging them into this mess before they even turn up. But I have to wonder, why ask if you are on Comcast? It's not hard to identify all of Comcast's IP space from the routing table, and they know the endpoint of every stream they serve. They have perfect data from their servers, why use error prone data from a survey? -- Leo Bicknell - bickn...@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ pgpdL3Fmq4dbz.pgp Description: PGP signature

I suppose this is all just a smoke screen to force one/both sides to upgrade inter-links before the l3/flix cdn contract goes whole hog. A stalling tactic and one to push buttons (political/PR buttons) raising the stakes/pushing timing up on installs... is interesting though. -chris
