2Africa is finished: the 45,000km subsea cable rewiring a continent

The Meta-backed 2Africa cable — longer than the Earth's circumference — is complete, connecting 33 countries and reaching more than 3 billion people. For African internet, it changes the economics.

One of the most ambitious infrastructure projects in the internet's history has quietly reached the finish line. 2Africa, the Meta-backed submarine cable that wraps the African continent, is complete — a 45,000-kilometre system longer than the circumference of the Earth, connecting 33 countries across Africa, Europe and Asia and putting more than 3 billion people within reach of its bandwidth.

It is now the longest open-access submarine broadband cable ever built, and the word "open-access" matters as much as the length. Rather than a single owner hoarding capacity, 2Africa is designed so that many operators can buy in, which tends to push wholesale bandwidth prices down — and in a market where mobile data can eat a painful share of a household budget, cheaper wholesale bandwidth is the difference between the internet being a tool and a luxury.

For Africa, subsea cable is not plumbing; it is destiny. International bandwidth has long been the continent's chokepoint, and projects like 2Africa and Google's Equiano have already improved connectivity and cut latency along the coasts. With the Pearls extension scheduled to go live in 2026, 2Africa's reach stretches further still, knitting African landing stations to the global internet with more capacity and more redundancy — the latter just as important, as the region's recent cable outages have shown how fragile single points of failure can be.

The timing is not coincidental. Every ambition Africa now nurses in AI, cloud and data centres runs on exactly this: fat, cheap, reliable pipes to move data in and out. A sovereign AI cloud in Nairobi or a fintech processing millions of transactions in Lagos is only as good as the bandwidth beneath it. 2Africa widens that foundation for a generation.

The exponential-growth angle is in what cheaper bandwidth unlocks downstream. Lower data costs pull more people online; more people online deepens the market for every digital business built on top — streaming, fintech, e-commerce, remote work. Undersea cable is unglamorous, but it is the layer everything else compounds on. With 2Africa complete, the continent's digital economy just got a bigger, cheaper on-ramp.
