The majority of people around the world, including George Clooney in “Gravity” believe that the Internet’s connectivity is provided by satellite communications. Not so, I hear the likes of the content providers such as Amazon, Facebook, Google, Microsoft, as well as all the telecommunications companies say. For the moment, they are correct in that about 99.5% of our international data and voice connectivity is provided over submarine fibre cables which cross-cross the world. The global submarine network is comprised of an estimated 213 independent fibre cable systems totalling c 550,000 miles (900,000 km) of fibre. Each year sees another 20-30 submarine cables systems being built to augment or replace the existing cables, provide additional diversity and connectivity enabling more capacity for the global Internet.
