About Vantage JNB1 Johannesburg Data Center Campus

Vantage JNB1 Johannesburg Data Center Campus, also known as Vantage JNB1 Johannesburg I, is a data center project in Midrand, Johannesburg, Gauteng, ZA associated with Vantage Data Centers. 30-acre Waterfall City campus; three data centers at full build; 650,000 square feet; 120 MW critical IT capacity. High-density campus with resilient power, closed-loop cooling and carrier-neutral connectivity near major cloud on-ramps. The current JNB1 project page markets 120 MW at full build, while Vantage’s 2022 opening release and current EMEA rollup imply an 80 MW JNB1 plan alongside 20 MW JNB2. the conflicting operator figures remain unresolved. Current operator evidence conflicts materially and does not establish a single project-scoped capacity figure.
