Submarine cables carry 99% of intercontinental data traffic — internet traffic, financial transactions, military communications — per the source's own words. This is not a redundant backup system for satellites; it is the network. Satellites carry a rounding error of the load this map describes.

A cable cannot come ashore anywhere. A usable landing point needs, per source: low marine traffic, a gently-sloping sandy or silty seafloor, and no strong currents to work the cable loose over decades. These conditions are not common along most coastlines — so independent cable systems, built by different companies on different continents for different customers, are repeatedly forced into the same narrow physical corridor because there is nowhere else geologically fit to land.

Two UNRELATED cable systems, built by different operators for
different purposes, forced through the same physical corridor
because that corridor is where the geography permits a landing.
On 25 December 2011, both cables were cut on the same day: SEA-ME-WE 3 (per source, the longest submarine cable on Earth, linking Southeast Asia to Western Europe) and the separate Chennai–Singapore i2i cable. The cuts were not coordinated — they were two independent failures sharing one corridor — and the result was real internet slowdown across South Asia, the Middle East, and the UAE the same day. The chokepoint is not a conspiracy; it is geology plus economics stacking unrelated infrastructure onto the same narrow strip of seafloor.

The same shape of incident — a cable found cut or dragged, intent disputed — recurs across more than 150 years, with attribution ranging from confirmed accident to confirmed act of war to permanently unresolved.

The pattern holds across 65+ years (1959 Novorosiysk to 2024 Baltic) and the verdict does not repeat automatically: the same corridor, the same suspected mechanism (anchor drag), produces one incident ruled an accident and another left permanently unresolved, sitting side by side in the same 15-month window. The map's honest shape is not "sabotage is happening here" — it is "this exact ambiguity has recurred, undecided, for over half a century."

As of 2024, roughly 200 undersea cables are cut or disrupted worldwide every year, per source — the overwhelming majority unintentional: fishing trawler gear and ship anchors, the ordinary hazards of shared sea lanes, not state action.
~200 CABLE FAULTS / YEAR, WORLDWIDE (source estimate, 2024)

The Baltic Sea incidents that earned NATO statements and named ships
are a visible sliver of a background rate that is, almost every time,
boring: gear dragged, anchor dropped, cable severed, repair ship sent.
This is the piece's real argument. Two mechanisms above — landing-point scarcity and recurring ambiguous attribution — describe genuine, documented, dated structural facts. But set against ~200 faults a year, the small handful that get a name, a date, and a diplomatic statement are the exception the map is built to notice, not the rule the map should imply. Most of the infrastructure carrying 99% of the world's data gets quietly cut and quietly fixed, all year, everywhere, without becoming a headline at all.
