    On-site personnel, 24 hours a day, 7 days a week, 365 days a year.

  • Biometric Authentication

    Biometric fingerprint, face, and iris scanning technology for giving your staff fast and secure access to your equipment.

    Our Hi-definition CCTV systems monitor all interior, exterior strategic locations and access points with video footage retained for security purposes to protect your hardware investment.


Cooling is a critical factor for hosted servers, telecommunications equipment and a prerequisite for any colocation data centre worth its reputation. For consistent, reliable, high-integrity services, equipment must operate within its optimum temperature and humidity envelope at all times.

Our total mechnical system is UPS backed in an n+1 configuration for your peace of mind. Our data centres provide the most efficient and resilient designs available on the market and meet our own stringent EODC (energy optimised data centre) philosophy.

The cooling solution is designed to maintain 24C +/- 2C at the front of every IT rack position 24 hours a day, 365 days a year.

Cooling throughout the colocation data centre is via highly resilient and economical indirect evaporative and adiabatic air conditioning units in an N+1 configuration, providing “free cooling”. For colocation suites we will build to your individual requirements, and have the cooling systems, margins and levels of redundancy that the customer specifies, from n to 2n resilience or greater.

The 5NINES cooling systems ensure your servers and co-located telecoms equipment is always operating within its optimum environmental conditions. The environment is immune to any failure in the cooling system or the electrical feeds to them.


The electrical systems in the 5NINES data centre are also designed to meet Tier 3 levels of reliability. Electrical powers is delivered to the data centre of dual fully-redundant feeds through a resilient ring structure. Both feeds from the substation continue to operate securely and reliably even f half of the ring is lost.

If a power feed fails, automated detection systems load-shed the data centre to on-site diesel generator plant. If both power feeds fail, a full automated switchover to diesel generator backup occurs.

This switchover is regularly tested to ensure that in times of crisis, your services continue uninterrupted.

Our on-site power generation capability is more than enough to power the whole 5NINES colocation data centre indefinitely. Twin generators to n+1 standards ensure full power performance even if one generator fails.

The on-site fuel tanks provide for 3 days continuous full load running, and contracted priority refuelling ensures emergencies. Our dedication to the efficiency of your data estate makes certain that no matter the crisis, 5NINES is there to resourcefully manage policies and processes against known and unknown factors.
