1. Story
2. The building where an ocean ends. A landing station is usually an unremarkable low structure set back from a beach, sometimes with no signage at all, and it is where the physical internet becomes visible for a few hundred metres before disappearing again into terrestrial fibre. Its functions are specific. The cable comes ashore through a buried duct or a beach manhole, so that the vulnerable surf zone can be maintained without excavating the beach each time. Inside, the power feed equipment supplies the direct current that runs the repeaters out to mid-ocean. The submarine line terminal equipment converts between the cable's optical channels and the terrestrial network, and it is the piece that gets replaced when a cable is upgraded. There is backup power, because a landing station that loses mains supply takes the seabed plant with it, and there is physical security, because everything in the building is a single point of failure for everything beyond it. Landing stations cluster: a small number of them — Marseille, Alexandria and Abu Talat, Fujairah, Singapore, Mombasa, Virginia Beach — carry a share of world traffic wholly out of proportion to their size, because a coast that is legally, commercially and geologically convenient for one cable is convenient for the next one too.

12. Supports the scale figures used in this pack: more than 600 active and planned systems and over 1.5 million route-kilometres in service as of early 2026, and the standard statement that submarine cables carry well over 95 per cent of international data traffic. V55 verification basis: retrieved by search, not opened — this session has no working WebFetch to telegeography.com. TeleGeography is a commercial research firm and is the de facto public register for this industry precisely because no public authority maintains one; the figures should be read as its counts on its own definitions, and they move every year.
13. Supports the landing-hub descriptions in this pack: the grouping of Singapore's stations at Changi and Tuas and the regulator's designated landing sites as of 2026; Marseille as a landing point for more than a dozen existing and in-development systems with dedicated port landing infrastructure; and the Egyptian station locations at Zafarana, Suez, Abu Talat and Alexandria. V55 verification basis: retrieved in summary, not opened. This is a commercial industry directory, and station counts in it change continuously.
