Meta has announced plans for Project Waterworth, an ambitious 50,000km subsea cable system set to be the longest in the world. The infrastructure project aims to enhance global connectivity by linking the United States, India, Brazil, South Africa, and other regions. Designed with 24 fiber pairs, the system will offer significantly higher data capacity, supporting Meta's growing AI-driven services and contributing to digital inclusion and economic growth in key markets.

The tech giant has been at the forefront of undersea cable development for over a decade, collaborating on more than 20 similar projects. With most of the world's internet traffic reliant on such cables, concerns over security have intensified, particularly as geopolitical tensions rise. In response to recent incidents, NATO has increased surveillance of critical maritime infrastructure, while the UK is reassessing its ability to safeguard its undersea network against potential threats.

Meta plans to lay sections of the cable at depths of up to 7,000 meters and employ advanced burial techniques in high-risk areas to minimise risks. This move follows recent disruptions, such as the damage to Tonga's undersea cable, which left much of the island in a digital blackout. Meanwhile, Meta's decision to scale back fact-checking on Facebook and Instagram has drawn criticism, highlighting the broader implications of its expanding digital footprint.
