Growing a World Wide Web

Every year Telegeography publishes a comprehensive, annually updated map that visualizes active and planned submarine telecommunications cables around the world. The futuristic looking 2025 Submarine Cable Map was released back in January. This map shows the current extent of the world’s active submarine telecommunications cables and those currently under construction.

The Internet Infrastructure Map allows you to see how the current network of submarine telecommunication cables has developed over the last 36 years. The map combines two key elements of the internet: submarine fiber-optic cables, which connect continents across the ocean floor, and Internet Exchange Points (IXPs), the data hubs where networks interconnect and exchange traffic.

One of the standout features of the Internet Infrastructure Map is its animated timeline. Starting from 1989, when the first modern subsea cables appeared, you can step year by year through time and watch the growth of the global internet unfold on the map. The animation reveals how over time the sparse early connections developed into the dense intercontinental webs of cables of today, with new systems being added almost every year. By sliding through to 2025, you can literally watch the internet’s backbone expand, seeing when major routes were built and how new IXPs shifted regional connectivity patterns.
