Ninety-nine percent of intercontinental internet traffic travels through cables lying on the ocean floor, each roughly the diameter of a garden hose. They are the least visible and most consequential infrastructure of the digital age.
For two decades, the cable map was drawn mostly by consortiums of telecom operators. That is changing. Hyperscalers now fund a majority of new routes, and governments have begun to treat cable ownership as a matter of national security.
Routes as leverage
A cable landing station is a chokepoint. It can be monitored, taxed, or cut. The countries that host the most landing points have quietly acquired a form of leverage that does not show up in trade statistics.
The map of the internet is a map of trust, and trust is being redrawn.
The next five years will see a construction boom: trans-Arctic routes, new links across the Pacific, and a rush to connect the fast-growing data economies of Southeast Asia. The cables will be laid by a handful of ships, insured by a handful of firms, and financed by a handful of companies. The world’s communications will run through fewer hands than ever.
