Johannesburg, South Africa – Data centers might not be the most glamorous topic, but a recent tour by Daniel Puchert of My Broadband of Teraco’s JB3 facility near Johannesburg’s OR Tambo International Airport proved to be a surprisingly fascinating glimpse into the technological backbone of South Africa.
Gone are the days of dusty server rooms. JB3 is a massive, four-story building that houses the critical IT equipment for businesses across the country. Think of it as a high-tech fridge, keeping vast amounts of data cool and accessible 24/7.
But keeping this digital fridge humming requires significant resources. JB3’s power needs are immense, with a total consumption of 60MW. That’s enough to run 30,000 homes! This highlights a key challenge for South African data centers: the country’s ongoing electricity supply issues.

While JB3 boasts a rooftop solar installation, it currently only provides a small portion of the facility’s needs. To address this, Teraco is building a dedicated 120MW solar plant, reflecting a growing focus on sustainable data storage solutions.
However, reliable power is paramount. Teraco employs a robust backup system with multiple layers of redundancy. This includes a fleet of powerful diesel generators that can kick in within seconds of a power outage, ensuring minimal disruption to client operations.

Another crucial element is cooling. Keeping the massive server racks from overheating is essential. JB3 utilizes a clever system that combines water-cooled air with filtered ambient air, creating a closed-loop system that minimizes water waste.
Security is naturally a top priority. Cameras and strict access controls ensure only authorized personnel can enter the data halls, which house row upon row of server cabinets.

The specific data stored within these halls is highly confidential, so photography inside the facility is strictly prohibited. However, the sheer scale of the operation, with dedicated co-location spaces for multiple clients, paints a vivid picture of the critical role Teraco plays in South Africa’s digital landscape.
