Source: DC Hub (dchub.cloud), facility records as of 2026-11-12. Verified sites that report MW only; blank means no MW reported. The "MW, all listings" tile above is a wider measure (every tracked site that reports MW, any status, unverified directory listings included), so it is larger than Total listed.
DC Hub does not hold a lease-rate figure for this market yet.
Teraco leads the operator roster with seven tracked sites, followed by Vantage Data Centers with four and NTT with three. The market has seen recent sector activity elsewhere in South Africa—Open Access Data Centres was acquired as a platform asset—but no recent deals have been tracked in Johannesburg itself.
This combination indicates that securing new power allocations will face both availability and infrastructure barriers. Operators expanding footprints here cannot rely on abundant spare capacity or frictionless grid access.
Deal flow into Johannesburg has stalled recently, with no tracked transactions recorded. Teraco's seven-site portfolio represents the largest operational presence, while Vantage's four facilities and NTT's three holdings reflect a market concentrated among established regional and global operators.
