Evaluating the scope and severity of downtime in critical industries

This report ranks the top seven critical industries based on the impact of a disruption in that industry. It also lists the top critical industries in terms of financial impact and identifies three emerging industries that are rising in criticality as they grow and evolve.

To some degree, criticality is subjective and dependent on the situation. The fact that one industry may rank slightly higher than another on a list of most critical industries doesn’t mean much if it’s your money or your reputation at stake. Almost every industry today relies on critical systems that can create significant value when they function as expected and significant disruption when they don’t.

Defining Criticality

In analyzing what makes an industry critical, we identified 15 criteria, encompassing the range of potential impacts from the loss of availability of critical systems, and weighted them based on the severity of the impact. These criteria were then used to create a criticality rubric that our panel of global critical infrastructure experts used to score the industries. They included:

  • Unplanned downtime’s impact on human health
  • Financial impact of unplanned downtime in terms of lost sales and opportunity
  • Societal order depends on availability
  • Potential environmental impact of unplanned downtime
  • Significant portion of the affected company's/affected affiliate’s resources depend on availability
  • Cost of recovery, including repairs, affected asset replacement, and alternate measures required during downtime
  • Immediacy of impact

  • Ripple effect from unplanned downtime
  • Likely scope (local, regional, national, global) of effects of unplanned downtime
  • Subjective industry criticality ranking
  • Impact of reputational damage caused by unplanned downtime in the competitive marketplace
  • Lack of availability causes frustration and angst
  • Unplanned downtime brings the risk of high media/public outrage
  • Probable duration of impact (operational, not reputational)
  • Industry's prioritization of availability

Industry Perspectives on Criticality

With Smart Cities, people are beginning to see the city as a system of systems.

Uptime, particularly of energy, is a primary concern of Smart Cities developers because the energy system is fundamental to the functioning of all other systems. This focus, combined with the limited scope of Smart Cities initiatives, makes them an ideal testing ground for technologies that enhance the reliability of the electrical grid by shifting some of the burden of reliability onto distributed systems.

Digital services are always on, and tightly integrated into our daily lives as consumers and in business.

Yet, the digitally connected world is still in its infancy and, if the last 10 years are anything to go by, the world will become more interconnected than it has ever been and the drive for availability will only increase. As this unfolds, global cloud and colocation providers, such as Equinix, will serve as the hub of interconnectivity, enabling businesses to respond quickly and evolve to implement new solutions to address changing market dynamics. Through our design architecture, operational procedures and utilization of leading equipment vendors, such as Vertiv, Equinix is delivering the highest level of availability for our customers today and laying the foundation for increased connectivity and digitization in the future.

Downtime is just not an option for cloud and colocation service providers anymore.

If you consider the critical financial, business and consumer applications now running on the cloud, serious downtime can have a huge impact on brand confidence and, ultimately, the bottom line. And the proliferation and usage of cloud and colo services is accelerating. As new markets and consumers look to ever-growing levels of data, and machine-to-machine communications increase through the Internet of Things and Industry 4.0, the availability of cloud and colo data centers is only going to become more and more critical.

While the world has grown increasingly digital, we are still heavily dependent on traditional industries, such as utilities, mass transit and telecommunication, which provide the day-to-day services that allow us to function in our personal and business lives.

At the same time, increasing digitization has created interdependencies across critical industries that are unparalleled. In almost every case, downtime in one industry has impacts that extend beyond that industry. Disruptions in the electrical grid ripple across all industries; delays in rail and air transport disrupt commerce; and downtime in a colocation facility extends across multiple businesses and shuts down the streaming video service we turn to for relaxation after a hard day’s work.

As this trend continues and new critical industries emerge, the critical infrastructure that supports these industries becomes more important than ever. Industries across the spectrum must continue to invest in the technology, processes and services required to keep critical systems operational. We may never be able to eliminate all natural disasters or human error, but with proper planning and investment, we believe we can achieve a world where critical technologies always work.


This non-scientific ranking was developed by our team of global critical infrastructure experts. First, they identified the 15 criteria that define critical systems, and then weighted each to create a “criticality rubric,” which panelists used, assigning a value of 1-5 for each criterion for each of 22 industries. When the weights were applied to these values, an aggregate score for each industry was computed. Averages for each industry were then calculated to develop the list of the most critical industries.
