Four fifty-three in the morning, the last day of the year. In a Finnish network operations room, a line on a screen falls over. Within hours, police and coastguard board a freighter with its anchor down and a scar tens of kilometres long on the seabed behind it. Fourteen people are taken off the ship.
That is not the important story.
More than ninety-nine percent of international data crosses the ocean floor inside glass fibre about as thick as a garden hose. Cables break roughly two hundred times a year, and between seventy and eighty percent of it is accidents — fishing gear and anchors. That number has barely moved in a decade, even though the amount of cable in the sea grew by half.
So the danger was never that someone cuts one.
It is that when a cable breaks, a ship has to sail out, drag a hook across the seabed until it catches, haul the broken end up over the bow, and splice it back together by hand — and the world has sixty-two ships that can do it. Most were not built for the job. Around two thirds reach the end of their working lives within fifteen years. Replacing them costs three billion dollars, and that money is not committed.
This film is about the gap between how reliable the internet feels and how thinly it is maintained.

The world's internet infrastructure is a complex and fascinating system, and few people know that there are 62 ships around the globe that play a crucial role in maintaining and fixing the internet. In this educational video, we delve into the history and technology behind these ships, exploring the science and culture that surrounds them. From the early days of the internet to the present, we examine the global mysteries that have shaped the development of this critical infrastructure. Across time, these ships have been instrumental in laying and rep
