That is why there's this neutrinos project
It's not faster than the speed of light though it can shoot through the Earth and no cables cost involved

So far the speed is 0.1 bit per sec


I bet for $ 1.5 billion neutrino communication (anywhere on Earth) to
its antipode in about 40 msec one way) could be
developed (i.e., the bit rate improved), and I could see some real
market advantages to anyone who had access to it, even
at 100 kbps type bit rates.

Given that, I wouldn't be too surprised to see some physicists and
networking people quietly being hired away by an
obscure new venture...

Can't wait for the neutrino SFPs :)

All three cables are being laid for the same reasons: Redundancy and speed.
As it stands, it takes roughly 230 milliseconds for a packet to go from
London to Tokyo; the new cables will reduce this by 30% to 170ms. This
speed-up will be gained by virtue of a much shorter run:




If they could armor the cable sufficiently perhaps they could drill the
straigh line path through the Earth's crust (mantle and outer core) and do
London-Tokyo in less than 10,000km.
