« Un tuyau de 6 600 kilomètres au fond de l’océan. Tel est le nouveau projet (très onéreux) de Facebook et Microsoft. Baptisé « MAREA » (la « marée », en espagnol), le câble de fibre optique partira de Virginie Beach, aux Etats-Unis, pour arriver à Bilbao, en Espagne. »
Bonne ou mauvaise idée, alors que les câbles nord-atlantiques sont très loin d’être surchargés ? Ou bien coup de pub ?

Dark fibre - Wikipedia, the free encyclopedia

(paragraphe absent de la version française)
One reason that dark fibre exists is that much of the cost of installing cables is in the civil engineering work required. This includes planning and routing, obtaining permissions, creating ducts and channels for the cables, and finally installation and connection. This work usually accounts for more than 60% of the cost of developing fibre networks. For example, in Amsterdam’s city-wide installation of a fibre network, roughly 80% of the costs involved were labour, with only 10% being fibre. It therefore makes sense to plan for, and install, significantly more fibre than is needed for current demand, to provide for future expansion and provide for network redundancy in case any of the cables fail.
Many fibre optic cable owners such as railroads or power utilities have always added additional fibres for lease to other carriers.
In common vernacular, dark fibre may sometimes still be called “dark” if it has been lit by a fibre lessee and not the cable’s owner.
Et dans l’article de Wired largement utilisé, ►http://www.wired.com/2016/05/facebook-microsoft-laying-giant-cable-across-atlantic ,
The data moved by just a few online giants now dwarfs that of most others, so much so that, according to telecommunications research firm Telegeography, more than two thirds of the digital data moving across the Atlantic is traveling on private networks—namely networks operated by the likes of Google, Microsoft, and Facebook.

ah oui, j’avais vu passer
y compris ton dernier tag, c’est peut-être parce que j’ai passé trop de temps à le lire que je n’avais pas été voir l’article pointé
