Two things I am curious about are 1) What is the measured benefit of moving a netflix server into your local ISP network
and 2) does anyone measure "cross town latency". If we lived in a world where skype/voip/etc transited the local town only, what sort of latencies would be see within an ISP and within a cross-connect from, say a gfiber to a comcast?
Once upon a time I'd heard that most phone calls were within 6 miles of the person's home, but I don't remember the breakdown of those call percentages (?), and certainly the old-style phone system was achieving very low latencies for those kinds of traffic.
The lack of decent geographic locality of reference on the Internet has bothered me for some time; it's often presented as an *effect* of the eyeballs/servers nature of the net, but I'm not at all sure it's not more a cause of it -- at least at this late date. The problem, of course, is that carriers make money off transit; it's not in their commercial best interest to unload those links; it's very similar to the reason my best friend's second semester pre-law textbooks cost her nearly $1000; the people selecting them have no interest in the price, since they don't pay it.
