Africa’s Undersea Internet Cables: What It Means for You

What happened

A recent report highlighted a major concern for Africa’s internet infrastructure: the continent has only one specialized ship capable of repairing undersea fiber optic cables that connect it to the rest of the world. These cables carry the majority of Africa’s internet traffic, ensuring that homes, businesses, and governments stay connected. When these cables break—which can happen due to storms, shipping accidents, or natural wear—repairs need to be swift to avoid widespread internet outages.

Unfortunately, having just a single repair ship means that any breakdown could take longer to fix. Delays could cause significant disruptions, affecting everything from online banking and shopping to remote work and education.

Why it matters

Undersea cables are often invisible to everyday internet users but are absolutely critical pieces of infrastructure. For Africa, these cables link the continent to global data centers and internet hubs in Europe, Asia, and the Americas. Given that Africa’s own infrastructure on land is still developing, smooth and reliable international connections are essential for economic growth.

When a cable goes down, the effects ripple across the economy. Internet speeds slow down, costs for data can rise, and some services may become unavailable. For a continent increasingly relying on digital services—especially since the Covid-19 pandemic accelerated online learning, e-commerce, and remote work—any weak point in connectivity can hurt productivity and exclude people from economic opportunities.

What this means for South Africans

South Africa is one of the most connected countries in Africa, with better internet infrastructure than many others on the continent. However, it still depends heavily on undersea cables that land along its coastlines for international connections. When these cables need repair, South Africa, like the rest of Africa, faces potential slowdowns and disruptions.

For ordinary South Africans, this could mean slower internet speeds during cable outages, interruptions in services like online banking or social media, and higher costs for mobile and home internet plans if providers need to cover extra expenses or purchase data from other sources.

For businesses, particularly those that operate online or rely on cloud services, unstable international internet connections can affect customer service, data access, and financial transactions. Small business owners who depend on smooth internet to market their products, take payments, or communicate with clients could find their operations affected during outages.

Impact on consumers, jobs and small businesses

Consumers may notice more than just slow internet. In sectors like education, unreliable internet can limit access to online classes and educational resources. For job seekers, especially those applying for jobs online or conducting interviews via video calls, disruptions can hamper opportunities.

Small businesses, especially those in digital services, e-commerce, and remote work sectors, face direct risks. According to recent trends, many South African startups and small enterprises operate online or rely on cloud-based systems. Any prolonged internet disruption could mean lost revenues, missed orders, and increased operational costs.

For job creation, the digital economy’s growth is crucial. Interruptions in internet can delay projects, disrupt communication, and reduce productivity—all factors that affect hiring and retaining employees.

Risks and limitations

The reliance on a single undersea cable repair ship highlights a vulnerability not only for Africa but for any region dependent on international internet cables. Shipping logistics, geopolitical challenges, and funding could limit the availability of repair services.

South Africa and other African countries might need to invest more in diversifying their internet infrastructure—building more local data centers, strengthening terrestrial connections, and encouraging private sector investment in cable repair resources. Additionally, governments could work together to develop regional strategies for better maintenance and quicker response to cable damages.

The challenges also point to the value of digital preparedness. Consumers and businesses can explore options like offline capabilities, multiple internet providers, or satellite internet services as backups.

While the current situation may seem like a technical issue, its consequences affect everyday lives and the economy of South Africa and the broader continent. Understanding and addressing these infrastructure vulnerabilities is critical as Africa continues to grow in the digital age.
