jokes aside, Its a hypothesis worth testing. It has qualities which make it plausible.
So please, between you, find a way to specify and test it!
although the hypothesis has some intuitive appeal, how to test it is far from obvious. and i note that, as a senior member of the measurement community, you're saying "you guys do it." thanks a lot. :)
i considered rtt from a service such as goog to their querriers. there are the problems of their distributed caches, the politics of getting their data, and the eyeball bias. maybe find a platform with less of those biases. dns is far too biased in all sorts of dimensions. your add clicks? i have found no usable coffee here in nagoya, so i may be missing something obvious.
Looking at my employers network... We know the GPS coordinates for each BGP next-hop in the network, and traffic is sampled on ingress at the edge of the network and reported to pmacct (*flow), which also receives a RR-style BGP feed for correlation. We can know where (geographically) a packet enters the network, where it leaves the network and to what address family it belongs. However, this would be just one network's (biased) view on things.
