Johannesburg: At A Glance

Network & Connectivity Ecosystem

Johannesburg stands as the most connected metro in Africa, making it the default choice for any latency-sensitive application serving the southern part of the continent. The market's maturity provides a deep and competitive environment for interconnection.

Carrier Density & Carrier Neutrality: With over 28 network providers, as of September 2025, the market offers exceptional choice. Carrier-neutral facilities provide redundant access to every major local, regional, and international network, ensuring optimal routing and cost efficiency.

Direct Cloud On-Ramps: Johannesburg provides direct, low-latency connections to major cloud providers, including AWS, Microsoft Azure, Google Cloud (GCP), and Oracle Cloud, as of September 2025. This allows for resilient hybrid cloud architectures across 5 distinct cloud regions.

Internet Exchange Points (IXPs): The market is anchored by NAPAfrica, one of the largest Internet Exchange Points on the continent, facilitating efficient, low-cost traffic exchange between networks. This drives down bandwidth costs and improves performance for participants.

Bare Metal: Bare metal services are readily available from multiple providers, with options from global players like Hivelocity and Latitude.sh.

Power Analysis

Power is a critical operational consideration in Johannesburg. While the grid has its issues, the data center industry here was built from the ground up to counteract them.

Average Cost Of Power: Industrial power costs are estimated between $0.11 and $0.14/kWh, as of September 2025. This pricing makes on-site generation and power efficiency critical components of total cost of ownership.

Power Grid Reliability: The national power grid faces significant reliability challenges. However, all major colocation facilities in Johannesburg are engineered with extensive N+1 or 2N UPS systems and multiple diesel generators with long-term fuel contracts to ensure uninterrupted uptime.

Market Access, Business & Tax Climate

Locating in Johannesburg provides more than just technical advantages; it offers a strategic position in Africa's most advanced economy.

Proximity To Key Business Districts: Data centers are strategically located with fiber access to key commercial hubs like Sandton, the city's financial district, enabling low-latency services for banking, finance, and enterprise clients.

Regional Market Reach: Johannesburg serves as the primary digital hub for South Africa and the broader Southern African Development Community (SADC) region, reaching a population of over 300 million.

Tax Advantage For Data Centers: While South Africa does not offer specific tax incentives for data centers, the country's established business framework provides clarity for foreign investment. The primary financial advantage comes from operating within the continent's most mature and connected digital economy.

Natural Disaster Risk

Johannesburg has a Moderate natural disaster risk profile, with an overall INFORM score of 4.8 out of 10, as of September 2025. The risk landscape is dominated by environmental factors rather than seismic or storm-related events. Key considerations for infrastructure planning include:

• Drought (8.8/10): A significant and recurring challenge, impacting water resources.
• River Flood (3.2/10): A moderate risk in specific low-lying areas.
• Earthquake (1.5/10): A very low risk.
• Tropical Cyclone (1.3/10): A very low risk due to the inland location.
