« The distance from Stanford to Boston is 4320km.
The speed of light in vacuum is 300 x 10^6 m/s.
The speed of light in fibre is roughly 66% of the speed of light in vacuum.
The speed of light in fibre is 300 x 10^6 m/s * 0.66 = 200 x 10^6 m/s.
The one-way delay to Boston is 4320 km / 200 x 10^6 m/s = 21.6ms.
The round-trip time to Boston and back is 43.2ms.
The current ping time from Stanford to Boston over today’s Internet is about 85ms (…)
So: the hardware of the Internet can currently achieve within a factor of two of the speed of light. »
