Colocation in Johannesburg directly translates to lower latency and higher performance for users across a dozen countries.

Johannesburg: At A Glance

Network & Connectivity Ecosystem

Johannesburg boasts the most developed and carrier-rich interconnection ecosystem in Africa. It serves as the primary peering point for the entire Southern African region, ensuring efficient traffic exchange and low-latency connections.

Carrier Density & Carrier Neutrality With over 25 unique network carriers present as of September 2025, Johannesburg offers excellent choice and competitive pricing. The market features numerous carrier-neutral facilities, preventing vendor lock-in and allowing direct access to a global roster of providers.

Direct Cloud On-Ramps The market provides direct, low-latency access to major cloud providers. As of September 2025, there are 5 cloud on-ramps enabling access to 5 distinct cloud regions. Providers with dedicated on-ramps include:

• AWS
• Google Cloud (GCP)
• Microsoft Azure
• Oracle Cloud

Internet Exchange Points (IXPs) The Johannesburg Internet Exchange (JINX), operated by INX-ZA, is the critical hub for local and regional traffic, keeping data within Africa and improving performance for end-users. Teraco's Africa IX also provides a major peering platform within its facilities.

Bare Metal Bare metal server options are readily available from multiple providers. Global suppliers like Hivelocity and phoenixNAP offer dedicated server solutions in the Johannesburg market for workloads requiring maximum performance and control.

Power Analysis

Average Cost Of Power Industrial power costs typically range from ZAR 1.80 to ZAR 2.50 per kWh, as of September 2025. While the grid is approximately 80% coal-powered, the cost structure is predictable for financial planning.

Power Grid Reliability The national power grid can experience instability, but data centers in primary corridors like Isando and Midrand are engineered to overcome this. Facilities feature extensive on-site diesel generation, multiple fuel suppliers, and advanced battery backup systems to guarantee uptime.

Market Access, Business & Tax Climate

Proximity To Key Business Districts Data centers are strategically located near key economic zones, including Sandton (the financial hub), Midrand, and the industrial and logistics centers around O.R. Tambo International Airport. This proximity provides low-latency connectivity for finance, manufacturing, and enterprise clients.

Regional Market Reach An infrastructure deployment in Johannesburg effectively serves not only South Africa's 60 million people but also provides a low-latency gateway to neighboring countries like Botswana, Zimbabwe, Namibia, and Mozambique.

Tax Advantage For Data Centers South Africa does not offer specific tax incentives for data centers. The country operates with a standard corporate tax framework and a 15% Value-Added Tax (VAT) on goods and services, providing a clear and established financial environment for foreign investment.

Natural Disaster Risk

Johannesburg has a moderate overall disaster risk profile, with a score of 4.8 out of 10 as of September 2025. The primary environmental hazards are related to climate and infrastructure, not seismic or storm activity.

Key natural hazards include:

• Drought: The most significant risk, potentially impacting water resources for cooling.
• River Flood: A moderate risk in specific low-lying areas.
• Earthquake: A very low risk, with minimal seismic activity in the region.
• Tropical Cyclone: Not a direct threat due to the city's inland location.
