The 31,000-mile cable will connect parts of the US, Brazil, South, Africa, and India. Project Waterworth should be online by 2030.

The social media giant says the multibillion-dollar project will connect the United States, India, Brazil, South Africa and other regions.

The company says the multi-billion dollar investment is needed to strengthen the reliability of the global internet and support AI innovation.

Enter Meta's mooted new internet cable, which is planned to be longer than the circumference of the Earth and up to four miles down into the sea. If that seems immediately counter-intuitive, such cables obviously don't just go in a straight line across the surface of the planet.

Meta has announced plans to build a 50,000km (31,000 mile) sub-sea cable across the world. The tech giant said Project Waterworth - connecting the US, India, South Africa, Brazil and other regions - will be the world's longest underwater cable project when completed.

Meta’s Waterworth Project will provide internet connectivity on five continents, with landing points in India, the United States, Brazil, and South Africa.
