This week, Meta’s engineering team shared a milestone that, in my view, could go down as a turning point in Africa’s digital transformation journey: the completion of the core 2Africa subsea cable system — now officially the longest open-access subsea cable network on the planet.

At a massive 45,000 kilometres, connecting 33 countries and touching more than 3 billion people, 2Africa isn’t just another infrastructure announcement. It’s a paradigm shift. It’s the kind of quiet, heavy-lifting engineering that rewires what’s possible for an entire continent.

As someone who has spent over two decades monitoring and documenting Kenya’s and Africa’s digital transformation— from the first mobile boom to the fibre backbone explosion, the rise of mobile money, cloud adoption, and now AI — this one feels different. It feels potentially pivotal.

Building A Pipe That Powers Africa’s Digital Future

What stands out immediately is scale. Very few infrastructure projects — anywhere in the world — attempt something this ambitious. But it’s the engineering details that really matter:

• 16 fibre pairs per cable, using advanced Spatial Division Multiplexing (SDM)
• A trunk capacity projected at up to 180 Tbps
• Intelligent optical switching for high flexibility and resilience
• Landings that span Africa, Europe, the Middle East, and Asia

What this translates to is simple: capacity, redundancy, reach, and affordability.

For the first time, Africa isn’t playing catch-up. We’re being plugged directly into the world’s fastest, most modern infrastructure at continental scale.

Why This Matters for Kenya — and Africa

It’s easy to get lost in the technical superlatives, but the true impact is human, economic, and societal:

1. Cheaper, faster, more reliable internet

This is not a theoretical benefit. Every new generation of subsea capacity has historically lowered wholesale bandwidth costs, boosted speeds, and improved redundancy. For countries like Kenya, where cloud services, fintech, and AI workloads are growing rapidly, this is critical.

2. A massive GDP uplift

The 2Africa consortium estimates that the cable could contribute up to US$36.9 billion to Africa’s GDP within just a few years. That’s not just “technology sector” money — that’s retail, manufacturing, logistics, agriculture, health, and education.

3. Real impact in underserved markets

This is the part that resonates deeply with me. Infrastructure like this makes it possible to reach communities historically left behind — arid regions, rural towns, peri-urban settlements. When capacity grows and wholesale costs fall, last-mile innovations suddenly make economic sense.

4. A catalyst for Africa’s AI and cloud future

Whether it’s generative AI, data centres, cloud gaming, remote work, or digital-first education, all of it depends on big, reliable pipes.

A Moment of Opportunity — If We Choose to Seize It

What I appreciate most about the 2Africa project is that it signals a broader shift: Africa is no longer waiting for the world to bring the future to us. We’re actively building it.

But connectivity is only one part of the equation.

Now we must ask ourselves — policymakers, entrepreneurs, telcos, cloud providers, educators, and innovators:

• How do we turn this bandwidth into meaningful economic gains?
• How do we ensure rural and peri-urban communities benefit, not just major cities?
• How do we nurture local content, local platforms, and local innovation?
• How do we build a digital economy where Africans are producers, not just consumers?

The infrastructure is here. The potential is enormous. What matters now is how we choose to build on it.

Key Takeaways

This is one of those rare inflection points — the kind we’ll look back on years from now and may say, that’s when things shifted. I genuinely believe 2Africa could redefine what is possible for Kenya and the rest of the continent across education, finance, health, manufacturing, agriculture, and the creative economy. 

The pipes are finally big enough. The question now is: What will we run through them?
