Just a preview:

Nearly 750,000 miles of cable already connect the continents to support our insatiable demand for communication and entertainment. Companies have typically pooled their resources to collaborate on undersea cable projects, like a freeway for them all to share.

But now Google is going its own way, in a first-of-its-kind project connecting the United States to Chile, home to the company’s largest data center in Latin America.

“People think that data is in the cloud, but it’s not,” said Jayne Stowell, who oversees construction of Google’s undersea cable projects. “It’s in the ocean.”

Getting it there is an exacting and time-intensive process. A 456-foot ship named Durable will eventually deliver the cable to sea. But first, the cable is assembled inside a sprawling factory a few hundred yards away, in Newington, N.H. The factory, owned by the company SubCom, is filled with specialized machinery used to maintain tension in the wire and encase it in protective skin.
