Hi Bill,

I take issue with this claim because:

And, "Of the total analyzed agreements, [...] 141,512 (99.51%) were
“handshake” agreements in which the parties agreed to informal or
commonly understood terms without creating a written document."

As a result, the data set suffers three flaws:

1. It is not representative of the actual traffic flows on the Internet.

2. The overwhelming majority of the agreements analyzed were handshake
agreements but no picture is available of the handshake agreements
those same parties rejected outright or, expecting rejection elected
not to pursue. That creates a data bias which could mask any number of
factors, leaving you no way to determine that the claimed norm bears
any resemblance to the results one might expect when proposing peering
with a neighbor.

3. The data supports no affirmative statement about the the peering
case most relevant to network neutrality: that of a small network
seeking to peer with a large one. More to the point, what agreements
occur or fail to occur when one network is in a position to strong-arm
the other and does this diverge from the general case?

That having been said, kudos for the excellent research. As far as
objective numbers go, yours are more thorough than any others I've
seen.

Regards,
Bill Herrin
