Hi Iljitsch,
I would not consider Sprint NAP, a place closed to new customers for several years, an important interconnect location in the US. ATM based IXs are not as participant rich as they were 2-3 years ago. The fastest growing US interconnect locations are cross-connect enabled. PAIX & Equinix. Equinix-Ashburn, PAIX-Seattle, Equinix-Newark and Equinix-Dallas and others have seen participation grow with a diverse blend of traffic from cable operators, telcos and content providers. Tier-1 means what? Look for growing sources of traffic. Your mileage may vary, -ren At 11:48 AM 5/17/2002 +0200, Iljitsch van Beijnum wrote: >A bunch of us are thinking about multihoming solutions for IPv6.
