Host in one of Africa's few Tier IV data centres

The majority of South African data centres are designed to Tier III principles, and many of them deliver excellent reliability. Alongside these, Rackzar operates infrastructure within Africa Data Centres JHB2 in Samrand, which holds Uptime Institute Tier IV certification and is one of only a handful of such facilities in Africa. Two of South Africa's largest banks host their own critical systems in the same facility.

Fault tolerantEvery power and cooling path has an independent twin. A failure on one path never reaches your servers.
Under 27 minutes a yearTier IV is designed for less than 26.3 minutes of downtime a year, against 1.6 hours at Tier III.
96 hours on generatorLoad shedding and grid failures are a problem for your office, not your infrastructure.
Banking-grade securityBiometric access, 24/7 security operations and a facility built for financial services.

Built for payment platforms, ERP systems, healthcare records and anything else where an hour of downtime costs more than a year of hosting.

Understanding Data Centre Tier Classifications

Data Centres with Certification

Tier ratings are awarded by the Uptime Institute, the independent body behind the Tier Standard. Many of South Africa's top data centres, including some of the country's largest carrier-neutral campuses, have not been through Uptime Institute certification and do not hold a formal Tier rating.

The absence of a Tier rating is not a reflection of a facility's quality. These data centres are engineered with redundant power, cooling and connectivity, and serve hyperscale cloud providers, network carriers and financial institutions. Without formal certification, however, they cannot be classified under the Tier Standard.
Each facility is therefore listed with the ISO and PCI DSS certifications it holds.

Africa Data Centres JHB2 in Samrand is the exception, having been awarded Uptime Institute Tier IV certification.

Rackzar partners only with enterprise-grade facilities built for continuous operation. Every site we use runs redundant power, cooling and connectivity, so your services stay up even when a critical component fails.

The Tier Standard defines four levels of data centre resilience. Tier IV facilities provide 96 hours of autonomous operation with complete fault tolerance through 2N or 2N+1 redundancy, while Tier III facilities offer N+1 redundancy with concurrent maintainability.

Specification	Tier I	Tier II	Tier III	Tier IV
Expected Uptime	99.671%	99.741%	99.982%	99.995%
Annual Downtime	<28.8 hours	<22 hours	<1.6 hours	<26.3 minutes
Redundancy Level	None	Partial N+1	Full N+1	2N / 2N+1
Concurrent Maintenance	No	No	Yes	Yes
Power Backup	N/A	N/A	72 Hours	96 Hours
Fault Tolerance	No	No	No	Yes

Uptime figures are the design availability for each tier, not a service guarantee.
