A carrier-neutral data centre gives equal, unrestricted access to multiple network operators, internet exchanges and cloud providers on-site, rather than requiring you to use one designated carrier.
OADC operates 11 facilities across South Africa, spanning Johannesburg, Cape Town, Durban, East London, Bloemfontein and Gqeberha. In addition, OADC has over 30 edge facilities located across the country.
Data centre costs in South Africa vary by rack space, power draw, redundancy level and contract length, so there's no single published rate to budget against. As a starting point, expect pricing to scale with three main variables: how much rack space you need (quarter, half or full rack), how much power you commit to per rack (measured in kW, not just used capacity), and the redundancy level required (N versus N+1). Cross-connects, remote hands and any additional power beyond your base allocation are typically billed separately, so ask for a full breakdown rather than comparing headline rack prices alone.
South Africa's relatively stable power grid (following an extended period without load shedding) has also started shifting cost conversations away from backup power premiums and toward long-term value: predictable, high-utilisation workloads generally colocate more cost-effectively than they would run in cloud, once ongoing usage-based billing and data egress fees are factored in. The most accurate way to budget is a tailored quote based on your specific rack and power requirements.
Reliability comes down to four things: certified design standards, redundant power and cooling, physical security, and network resilience.
Tier certification. A Tier III designed facility, certified by the Uptime Institute, confirms redundant infrastructure that allows maintenance without disrupting operations. This is the clearest independent signal of reliability available.
N+1 redundancy. This means the facility has at least one additional unit of power or cooling capacity beyond the minimum required, so a single component failure doesn't cause downtime.
Physical security. Multi-stage access control (commonly cited as 7-level access control in South African facilities) and 24/7/365 monitoring protect against both digital and physical risk.
Power resilience specific to South Africa. Given the country's history with load shedding, ask specifically how a facility is engineered to maintain uninterrupted operations through grid disruptions, not just what its stated uptime percentage is.
Carrier-neutral connectivity. A facility offering access to multiple carriers, rather than a single provider, reduces the risk of an outage on one network taking your connectivity down with it.
Yes. OADC facilities are engineered with redundant power infrastructure and backup systems specifically designed to maintain operations through extended load shedding.
Start with location, then work through infrastructure, connectivity and commercial terms in that order.
Location. South Africa's main hubs are Johannesburg (South Africa's largest economic and connectivity hub), Cape Town (Western Cape's commercial centre), and Durban (KwaZulu-Natal, with direct 2Africa subsea cable access). Choose based on where your users, staff or partners actually are, and whether you need a secondary site for disaster recovery in a different city.
Certifications. Confirm current Tier rating and ISO 27001 status directly with the provider rather than relying on marketing claims, since certifications can lapse or apply only to specific facilities within a wider network.
Power resilience. Ask specifically how the facility performed during past load shedding periods, not just its theoretical redundancy design.
Connectivity. Check whether the facility is carrier-neutral (equal access to multiple network providers) and whether it has direct subsea cable access for international traffic.
Scalability. Confirm how easily you can add capacity later, whether more racks, more power, or expansion into a different South African city within the same provider's network.
Track record. A provider with multiple facilities and a longer operating history offers more predictable service continuity than a newly built single site.
OADC Durban (DUR1) is the landing point for the 2Africa subsea cable into KwaZulu-Natal, one of only four 2Africa landing points on the South African coast.
Data centre refers to the physical facility itself. Colocation is the service of placing your own hardware inside that facility. Every colocation provider operates a data centre, but not every data centre offers third-party colocation.
Johannesburg is South Africa's largest connectivity and economic hub, generally offering the widest carrier and cloud ecosystem. Cape Town is the stronger choice if your operations, customers or compliance requirements are concentrated in the Western Cape. Many businesses use both for geographic redundancy.
OADC Isando is Tier-III design complaint. Its infrastructure meets international standards for redundancy and availability.
