Why the Smartest strategy for CIOs managing risk is Operational Certainty
How reliable is your digital infrastructure?
Reliability is the foundation of trust in digital infrastructure. Every modern organisation, across financial services, healthcare, government, global technology or any other vertical you care to name, now depends on uninterrupted access to critical systems and data. Today, and even more so into the future, that is non-negotiable and fundamentally, it is what customers expect their service providers will deliver.
The reality, however, is that reliability can never be taken for granted. To have complete faith in your digital infrastructure, it must be deliberately engineered, proven in practice, and independently verified over decades of operation. In a world where milliseconds matter and downtime can literally cost millions of dollars or even human lives, reliability has become the most valuable and often overlooked trust-currency for digital infrastructure.
What customers should look for in a reliable DC partner
Reliability is not a claim. It must be evidence-based and independently verified. When evaluating a provider, customers should ask:
- Are facilities independently audited and certified? Self-assessment is never enough.
- Are efficiency ratings independently verified? (e.g. transparent PUE, NABERS).
- Is the facility design truly fault tolerant? UI Tier IV certification at the design, built and operational stages ensures no single point of failure.
- Is there continuity of expertise? The same in-house engineering team should design, build, and operate facilities over decades.
NEXTDC consistently meets these benchmarks, so that we can deliver the operational certainty, future-readiness and strategic advantage our customers are seeking. We continue invest strategically strive tirelessly to set standards for sovereign-scale, world-class data centres.
“The NEXTDC Engineering and Design team’s mission, since foundation of the company in 2010, has prioritised reliability and sustainability as the key targets of all NEXTDC projects. When we hand over the data centre to the facilities management team, we must know that it is truly N+1 fault tolerant and has passed the most rigorous design and testing in the industry.” – Jeff Van Zetten, Chief of Engineering and Design at NEXTDC.
Why reliability matters
For boards and CEOs, reliability is about protecting reputation. It’s about compliance. It’s about business continuity and it’s about delivering stakeholder value. In today’s digital economy, where data has become the most valuable commodity on the planet, a single outage can trigger revenue interruption, regulatory scrutiny, customer outrage, and/or front-page headlines. In summary, downtime is a disaster.
According to the Uptime Institute’s (UI) 2025 Annual Outage Analysis, 54% of respondents said their most recent major outage cost more than US$100,000 while 20% reported a cost exceeding US$1 million. That doesn’t consider reputational damage but, in anyone’s language, that represents significant financial impost.
For CIOs, reliability means predictable cost of ownership and a platform of resilience they can trust, and plan around. For IT leaders, the true cost of downtime is not only lost revenue but also the diversion of resources, remediation efforts, and opportunity costs from time-to-market impact on projects. CIOs know well that outages can and do have immeasurable effects that ripple across entire organisations.
For CTOs and digital leaders, reliability underpins the ability to innovate with agility and flexibility. It ensures next generation, data-driven AI and high-performance workloads can scale with confidence. Unreliable infrastructure doesn’t just create risk, it actively stifles growth and innovation.
Meanwhile, for operations teams, reliability is about certainty. It means they can deliver services seamlessly to customers without the stress of second-guessing whether the platform will hold up under pressure.
Any way you look at it, reliability can no longer be a mere back-office metric. It is the engineered basis of trust. It is the foundation upon which resilience, scalability, and customer confidence are built.
How NEXTDC designs, engineers and delivers reliability
- Power Systems: We engineer for failure, so customers never experience it.
Power failures remain the number one cause of outages worldwide (UI). At NEXTDC, our philosophy is simple: anticipate failure and design it out. Every data centre we operate is built with N+1 fault tolerance, including generators, UPS systems, switchboards, and dual isolated power feeds. Therefore, if one path fails, another instantly takes over. In over 15 years of operation, NEXTDC has delivered premium data centre services against a 100% uptime guarantee. - Cooling Systems: Scaling AI requires cooling you can trust.
Cooling failures are one of the most common and hidden causes of data centre outages. In the past decade alone, the headlines created by cooling system failures have included chaos at Sydney Airport from an airline outage, a major betting system going down during Australia’s Melbourne Cup carnival and enterprise collaboration platforms going offline across Asia-Pacific when cooling systems tripped. The bottom line? With AI and HPC workloads driving unprecedented heat densities, cooling integrity is now a frontline business risk. For tomorrow’s digital infrastructure, there is genuine peace-of-mind that can be realised from having complete confidence in the reliability of your cooling systems. - People and Processes: Certified, audited, accountable.
Globally, human error contributes to almost 40% of outages, according to UI. At NEXTDC, we mitigate this through disciplined operations validated by independent authorities. NEXTDC is proud to offer Tier IV Gold Operational Sustainability certification. This is the highest global standard of operational excellence which is complemented by our internal National Operational Excellence (NOE) scorecard which tallies resilience, security, customer experience, network and maintenance performance. Together they form the foundation of our commitment to zero downtime. - Lifecycle Choices: We build for decades, not years.
Many providers focus on short-term cost savings, but systems with shorter lifespans create hidden risks and long-term expenses. NEXTDC designs for the long game. Our facilities are designed and operated for 25+ year infrastructure lifespans that reduce replacement risks and ensure extended continuity.
Reliability and the Five Ss of NEXTDC Brand Promise
Reliability at NEXTDC is inseparable from our five brand pillars:
- Speed: Delivering capacity where and when customers need it.
- Scale: Seamlessly supporting deployments and workloads from 1MW to 500MW.
- Security: Protecting data, systems, and reputations to the highest international, government and industry standards.
- Sustainability: Building future-ready, energy- and water-efficient facilities at scale.
- Sovereignty: Ensuring data stays within the jurisdiction of its host nation (across Australia and our Asia-Pacific markets.
Together, these five dimensions reinforce the foundations of trust. Customers choose NEXTDC not just for uptime, but for the certainty that their digital future is secure, sustainable, and sovereign.
Reliability as the engineered basis of trust
Reliability is engineered, not assumed. It is the outcome of rigorous design, disciplined operations, independent validation, and decades-long lifecycle thinking. It is how NEXTDC deliver operational certainty today, future readiness for tomorrow, and market trust for the long term.
As workloads grow in scale and criticality, resilience becomes the only true currency of trust. NEXTDC stands ready to prove it, showing how reliability underpins every aspect of our customer promise.
