The Red Sea cable corridor

1. Story
2. A sea about 2,000 km long and, at its southern gate, some tens of kilometres wide, through which the great majority of cable traffic between Europe and Asia passes. Geography leaves almost no alternative: a cable from Europe to India or Singapore either goes this way — Mediterranean, Egyptian land crossing, Red Sea, Bab el-Mandeb, Gulf of Aden — or it goes the long way round the Cape of Good Hope, adding many thousands of kilometres of cable and tens of milliseconds of latency, or it crosses the Pacific from the other side. Retrieved analyses of the corridor describe on the order of sixteen systems running its length. The concentration is therefore extreme at both ends and along the middle, and the corridor has three distinct kinds of exposure stacked on top of each other: a narrow, shallow, heavily anchored southern strait; a war in which shipping has been attacked and in which one sunk vessel's dragging anchor severed several cables at once in early 2024; and a repair regime that requires permissions from coastal states whose waters are contested. It is, on the published analyses, the most concentrated and the most exposed single corridor in the system.

19. Evidence
20. Supports the account of the Egyptian land crossing: on the order of ten landing stations and ten or more terrestrial routes under a single national operator, roughly sixteen systems along the Red Sea, and the estimate that more than 90 per cent of Europe–Asia communications traffic crosses Egypt. V55 verification basis: retrieved in summary, not opened. These are ANALYST ESTIMATES, not measurements — the same retrieved material gives Egypt's share of global traffic as anywhere between about 17 and 30 per cent, which shows how wide the uncertainty is — and this pack attributes them rather than asserting them.
21. Supports the 2024 and 2025 Red Sea incidents as described here: the cables reported affected, the assessed anchor-drag mechanism in 2024 with ICPC comment, the 05:45 UTC start of the September 2025 latency effects, and Microsoft's statement that traffic previously routed through the Middle East would see higher latency. V55 verification basis: contemporaneous journalism retrieved in summary, not primary incident reports. Cause attribution for the 2024 damage is an assessment, not a finding; the Houthi movement denied involvement in the 2025 cuts and no cause has been established here.
