The first problem is to identify what defines a site.
Is an ASN a site? Would all of AS701 be considered a single site?
then, how can one identify a site. Is a prefix a site? What about
that are aggregated and span multiple locations all over the world?
There is no clear correlation between routing data and any logical
of the term site. Is a site a building, a campus, the collection of
networked in a given metro. area? There isn't even a clear definition
term site, really.
If you can define what it is you want to measure, then, perhaps it
measured. However, the question as stated cannot be measured because
the terms used are not sufficiently defined as to allow measurably
