another datapoint: 768k SDSL. 10-11 msec RTT to my ISPs peering connections
with other networks. end-to-end RTT of 14 ms, over twice the physical
distance (a whopping 22 miles) compared to circa 9ms times to the same
location(over 12 mi end-to-end) from a real T-1 local loop. Wire distance
on the DSL is about 6k ft. The T-1 loop is less than 900 ft. Everything
past that 'last mile' is T-3 or better.
I can live with an added 5ms.
