Basically it all there so that the UK/US stock exchange can communicate 30ms faster. This enables billionaires to make billions more.
The upside apparently is that for $200 all those in the starving 3rd world countries can buy a flat panel satellite receiver to get the internet.

This is all just for one network, there could be another 4 or 5 in the future.
