SpaceX aims to provide internet coverage with Starlink constellation as soon as mid-2020

“Starlink is SpaceX’s proposed constellation of thousands of satellites, which are designed to orbit at low altitudes above the Earth and beam internet coverage to the surface below. SpaceX has so far secured licensing from the Federal Communications Commission to launch nearly 12,000 satellites into orbit. And just last week, the company submitted another request to an international regulator, the International Telecommunication Union (ITU), asking for radio frequencies to communicate with an additional 30,000 Starlink satellites. That means the company wants the ability to launch an estimated 42,000 satellites into orbit.”

“Google est impliqué dans 15 câbles sous-marins: la société californienne fait partie de 11 consortiums et est l’unique propriétaire de quatre câbles, selon le site spécialisé dans les télécoms Telegeography.com. Facebook est impliqué dans dix projets, Amazon dans cinq et Microsoft dans quatre câbles. En 2012, les géants de la tech possédaient moins de 10% des capacités de transmission des données sous l’eau. Désormais, cette part est de 54%, selon Telegeography.com, qui s’attend à ce que cette proportion atteigne les 90% d’ici quelques années.”

Seeing a black hole with half a ton of hard drives

“That would mean they transferred 700 terabytes in 50,400 seconds, for a final data rate of about 14 gigabytes per second. As Marrone said, if you’re dealing in petabytes of data, the fastest bandwidth you can buy is not the Internet—it’s putting your hard drives on an airplane and flying them to your destination.”

Cyberstructure. L’Internet : un espace politique, de Stéphane Bortzmeyer

Cyberstructure L'Internet : un espace politique

“Une grande partie des activités humaines se déroule aujourd’hui sur l’Internet. On y fait des affaires, de la politique, on y bavarde, on travaille, on s’y distrait, on drague… L’Internet n’est donc pas un outil qu’on utilise, c’est un espace où se déroulent nos activités.” – Stéphane Bortzmeyer @bortzmeyer

What is the internet? 13 key questions answered

Telegeography 2018

“The internet is the wider network that allows computer networks around the world run by companies, governments, universities and other organisations to talk to one another. The result is a mass of cables, computers, data centres, routers, servers, repeaters, satellites and wifi towers that allows digital information to travel around the world. It is that infrastructure that lets you order the weekly shop, share your life on Facebook, stream Outcast on Netflix, email your aunt in Wollongong and search the web for the world’s tiniest cat.”
