Facebook 1 billion dollars to build global data center Network

Facebook reports in its SEC document that it has a "network of devices" worth 1.016 billion of dollars.

One thing is for sure: Facebook's network can only grow bigger. "We plan to continue to significantly expand the size of the infrastructure," the company said. "We will invest in Facebook's data centers in the US and beyond Europe, and our goal is to deliver Facebook products quickly and reliably to all users around the world." ”
