Indeed. However, isn't Florida one of the regions Comcast picked up from Road Runner? Perhaps Comcast hasn't, yet, built out their backbone in the Southeastern U.S.?
One Global Crossing (Tier 1 backbone provider) hop between ATTIS (my provider's backbone) and Comcast's 'ibone' network.
One Level 3 (Tier 1 backbone provider) hop between ATTIS (my provider's backbone) and Comcast's 'ibone' network.

All connections to West Coast destinations are made right here in San José, California.
Seven Level 3 (Tier 1 backbone) hops between ATTIS in San José, California and the Comcast 'ibone' network in Chicago, Illinois.

I would guess that Comcast just has to put in their 'ibone' in the Southeast, based on trace routes to '.hsd1.ga.comcast.net' and '.hsd1.fl.comcast.net' from the West Coast.

It should only affect DSL prices related to the DSLAM and ATM networks for at&t Yahoo! HSI subscribers. There should be no impact on the ILEC DSL prices in AT&T Southeast (the former Bellsouth FastAccess, which is now called, "AT&T FastAccess), or the reselling of CLEC services outside of the AT&T ILEC footprint (AT&T Worldnet DSL Service, which resells Covad connections; and their prices are controlled by the regional ILECs serving Covad). Nor should it directly impact the AT&T Tier 1 backbone (AT&T Worldnet Services, or ATTW), which provides transit to Comcast in Florida.

Do remember, before AT&T bought Bellsouth, SBC bought AT&T. The only thing SBC changed was the name of the company; management is still the same as it was under SBC.

ATTIS will only connect with ATTW when routing tables call for it.

You, as an at&t Yahoo! HSI customer, will be on the ATTIS network until it connects with a destination transit provider, as announced in BGP by the destination.

P.S. I forgot to mention that ATTIS will connect directly to Google, Microsoft, and Yahoo! networks, without going through any other transit. At least for all trace routes I have ever run to them.

Nearly all of Comcast traffic here used to go through AT&T a couple years ago.
Not anymore!
For some routes, sure! AT&T, Gblx, Level3...
For *most* things, here in my part of the State, it stays on Comcast across the country.

For that Yahoo address you used: 209.191.93.52...


No AT&T here - I see Level3.
Comcast will peer with whomever is closest if needed.
Not just AT&T.
For most national backbone tasks, Comcast will use their own - for many of us!

YMMV

They do it the same reason why my company uses it. When you request multiple pops from them it is much cheaper to get connections out all over the place. Main issue is when they upgrade core routers and they take a dive , it brings down the whole network.

AT&T is just cheaper if you want diverse pops. I wish Verizon would do something to lower their diverse pop prices. I hate seeing my work traffic all going over at&t , I want to see diversity.

Yes, on occasion Comcast does peer with AT&T for some things, but Comcast does have Nation Wide backbone itself.
