Colocation makes exceptional business sense. The economies of scale achieved in a purpose-built data centre far outweigh the benefits of trying to keep it all under your own roof.  It’s cost-effective and offers you high performance, reliability, availability, security, flexibility and service levels.

You leverage hosting of world-class quality to colocate your IT applications, networking equipment and business continuity solutions with 140 data centres globally.

From simple space and power requirements to an array of managed hosting services, choose the right option for you according to your needs for management and internal IT staff and skills. We’re a global one-stop provider with the option of additional services you need now or may need in the future.

NTT ICT’s data centres have been built to the highest industry standards and fitted with advanced security and performance features. They meet Tier III requirements as classified by the Uptime Institute and are directly connected to our industry-leading IPv6 compliant, Tier 1, global IP network backbone. With infrastructure engineered to a minimum of fully redundant N+1 or N+N standards, we ensure business continuity and the availability of your IT systems with no single point of failure. Advanced cooling and humidity control provide an optimal environment for server infrastructure.  


Our data centre services are engineered to deliver:

  • Reliability: Many organisations simply grind to a halt when their IT infrastructure is struck by power outages. When your IT operations are colocated within an NTT data centre, it’s business as usual. With an uptime record second to none, our Tier III facilities promise over 99.982% uptime. We have been operations since 2002 with around-the-clock monitoring and 24x7 on-site support ensure that systems are always fully operational and someone is always on the ground, ready to assist in the event of a problem.

  • Performance: Power available when you need it, delivered redundantly.
  • Location:  Our local facilities are always central to the CBD they serve.
  • Energy efficiency: Purpose-built data centres are typically 20–40 per cent more energy efficient than office-based facilities. This is due to efficient internal distribution systems, and high-voltage, low-loss connectivity to the power grid.
  • Flexibility: With a range of power, rack and security options, we are the most flexible service provider in the market. Options from single RU in conjunction with Cloud environments, up to full racks with between 2 and 12kW of power allocation, and private environments designed to enhance security and support power loads of up to 25kW per rack using hot-aisle containment, cold-aisle containment, and water cooled solutions. Pick and mix to suit your needs. Additional services such as Smart/Remote Hands, Managed Infrastructure and Cloud services, Tape Management and Configuration give you greater options and flexibility. What’s more, with a myriad of carriers available at each location, we’re carrier-neutral and you won’t get tied to a specific telco.
