The independent atlas of the world’s undersea cables
Every undersea cable on Earth — who owns it, where it lands, what it cost, and which ship laid it. Born as the official home of the Coral Sea Cable System, now mapping the internet’s entire deep-sea backbone.
Explore the atlas
Compiled from primary sources — operator announcements, procurement records and the public record — and updated as the network grows.
- The cables
Every submarine cable system — routes, owners, suppliers, capacity, cost and status, from the trans-Pacific giants to single-island links.
- By country
How each nation touches the global network: the cables that serve it, where they land, and how resilient the connection really is.
- The fleet
The specialist ships that lay and repair the world’s cables — specs, ploughs, ROVs, and the maintenance zones they guard.
- The industry
Suppliers, installers, surveyors and consultants — track records, case studies and publicly documented tender awards.
- Tenders
Who won what: cable contracts and procurement outcomes from the World Bank, ADB, DFAT and beyond, from the public record.
- The CS² archive
This domain’s first life: the official build diary of the Coral Sea Cable System (2018–2020), preserved as published.
