Meta has unveiled its most ambitious subsea cable project to date — Project Waterworth, previously referred to as "W", because of it's shape. The multi-billion-dollar initiative is set to become the longest subsea cable in the world, spanning over 50,000 km and connecting five major continents, including the U.S., India, Brazil, and South Africa. With 24 fibre pairs delivering the highest capacity technology available, Project Waterworth will redefine global digital infrastructure and enhance connectivity for billions of users.
Subsea cables form the backbone of the internet, carrying more than 95% of intercontinental traffic and enabling global communication, financial transactions, and AI-driven innovations. With this latest venture, Meta aims to open three new oceanic corridors, ensuring high-speed, reliable connectivity that will power the next wave of AI advancements worldwide. By leveraging cutting-edge routing techniques, enhanced burial methods in high-risk areas, and deep-sea deployments up to 7,000 metres, Project Waterworth is designed for maximum resilience and security.
India at the Centre of Meta’s Connectivity Vision
India is central to Meta’s strategy, with its platforms—Facebook, Instagram, and WhatsApp—serving over a billion users in the country. With AI adoption accelerating, demand for data centre capacity and seamless connectivity is at an all-time high. Project Waterworth is expected to play a pivotal role in supporting India’s digital economy by providing the necessary infrastructure to handle AI workloads, cloud services, and high-speed internet demands.
The project also underscores Meta’s shift in subsea cable strategy. Unlike its earlier 2Africa initiative, which followed a consortium approach, Project Waterworth appears to be a fully owned and controlled system. This mirrors Google's model of securing dedicated infrastructure for strategic markets rather than relying on shared capacity. While this approach ensures end-to-end control and security, it diverges from the collaborative model that has been highly successful in previous large-scale subsea cable projects.
Bypassing Global Chokepoints
One of the key aspects of Project Waterworth is its avoidance of politically sensitive and high-risk regions. Meta has reportedly designed the cable to steer clear of the Red Sea, the South China Sea, Egypt, and the Malacca Strait—areas that have become significant geopolitical bottlenecks for global internet traffic. By taking a direct route between the U.S. and India with strategic stops in South Africa and potentially Australia, Project Waterworth aims to ensure long-term security and avoid the risks associated with conflict zones and regulatory challenges in transit countries.
However, this bypassing of traditional routes does come with a trade-off: increased latency. Despite this, Meta appears to prioritise long-term security and reliability over marginal improvements in data transmission speeds. The project will also likely face regulatory hurdles, particularly in India, where obtaining permits for marine surveys and installations is notoriously complex and time-consuming.
The Battle for AI Connectivity Dominance
Meta’s decision to fully own Project Waterworth could have wider implications for the subsea cable industry. If Meta excludes partners, it may push competitors like Google to develop their own dedicated infrastructure to serve India’s growing digital ecosystem. Given the scale of investment—potentially exceeding $10 billion over the next decade—this move signals a new era of tech giants building independent, AI-optimised connectivity solutions.
While Project Waterworth marks a significant leap forward in global connectivity, the challenge will be balancing rapid deployment with regulatory constraints. If successful, it will not only strengthen Meta’s position as a digital infrastructure leader but also cement India’s role as a global AI powerhouse in the decades to come.
