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?
On average, 1ms for every 100km. We've seen this in practice - consistently - for any fibre deployed within the same town/city. Unless someone does something very wrong with the fibre, suffers terrible hardware issues, deliberately implements debilitating bandwidth management or does a piss-poor job of network design, it would be reasonably hard to go above +/- 1ms for traffic that originates and terminates within the same town, let alone 6 miles of speaking parties.
