True numbers? I don't think it is against the rules to say that Google is paying less then $10/meg to some providers for transit. Where the information comes from, and the exact numbers that you want however are covered under NDA's and the like. That, and they also have peering arangements with a great many.

This breaks down along the lines I was mentioning. The "Crawler" is transit traffic, as being nearly 99% "suck" traffic it would kill any peering arangement out there. The peering is the service provider side of Google, www.google.com etc.

The reality is that any provider that has a ratio bent toward content providers would kill to "Give" google transit to prop up their "Eyeball" traffic and even out ratios.

It's really not that hard a concept. They get nearly free transit to index/download everything they can find, and use peering (totally free) to serve www.google.com
