Peering
Given the recent articles about the spat between Netflix and Verizon (who by all accounts appears to have signed peering agreement) it seems uncertain how much this well help AT&T. Verizon seems to have done theirs in April and yet its customers report issues with Netflix. Sure some provisioning can take some time but three months? Also makes the public bickering somewhat odd if an agreement in place. I suppose that is where L3 come in being the carrier between the two.
Shall be interesting to see if AT&T fares any better than Verizon.
