Overview
Infrastructure
Tier guide →- Connectivity
- Cassava Technologies pan-African fibre-optic network (high-speed, ultra-low-latency), Oni-Tel Fibre Networks 'Infinity' interconnection platform — dark fibre, carrier-grade, high-capacity, ultra-low-latency connectivity
Pan-African fibre network owned by Cassava Technologies, described as high-speed ultra-low-latency. Oni-Tel partnership (announced 2026, per s3) adds dark fibre and carrier-neutral interconnection via the Infinity platform, specifically named for the Midrand and Samrand campuses.
Cooling adequacy for AI workloads has not been independently assessed for this facility.
AI data centres require ~100 kW/rack (10× conventional). Liquid cooling at rack level is the key differentiator. Learn more →
Power

- Eskom
- Grid carbon intensity
- 900 g CO₂/kWh
- PPA partners
- Distributed Power Africa
Eskom grid average ~900 gCO₂/kWh per Eskom Integrated Reports (2022-23). Grid-level figure, not facility-specific.
12MW solar farm near Bloemfontein with Distributed Power Africa, powering ADC SA portfolio under wheeling.
Grid carbon context
900 g CO₂/kWh — Very high — coal-heavy grid
2.1× the global average (436 g CO₂/kWh, IEA 2022). Compare: France ~60, UK ~175, US ~400 g CO₂/kWh.
Grid-level estimate. PPAs and on-site renewables may reduce the effective carbon footprint.
