Howdy,

Why is latency between the east and west coasts so bad? Speed of light
accounts for about 15ms each direction for a 30ms round trip. Where
does the other 30ms come from and why haven't we gotten rid of it?

c = 186,282 miles/second
2742 miles from Seattle to Washington DC mainly driving I-90

2742/186282 ~= 0.015 seconds

Thanks,
Bill Herrin
