The 2026 Global Data Center Survey from Uptime Institute reveals an industry navigating workforce constraints, escalating outage expenses, even as rising costs remain the top concern for management teams.
Financial Pressure and Resource Constraints Intensify
While high costs continue to be a primary concern for data center leaders, the 2026 survey also highlights escalating concerns over capacity forecasting, power availability, and supply chain disruptions.
Power efficiency gains remain gradual. The industry saw minor improvements in average Power Usage Effectiveness (PUE) levels this year. While newer facilities may boast highly efficient designs, overall global progress is slowed by legacy infrastructure.
The AI and Density Reality Check
Despite market enthusiasm for Artificial Intelligence, expectations for AI in data center operations cooled slightly in 2026. Operators express the highest levels of trust for lower-risk AI applications, such as sensor data analytics and predictive maintenance, rather than autonomous control.
Power demands per rack are climbing, driven by AI but also by other enterprise applications. Average modal rack densities continue their slow upward trajectory, with a growing number of operators now reporting peak rack densities of 30 kW or higher to support advanced computing workloads.
Outages: Fewer Incidents, Higher Price Tags:
The 2026 data shows a positive, long-standing trend: fewer operators reported experiencing an impactful outage over the past three years. However, systemic risks are an emerging concern. One in ten outages is still classified as serious or severe, and the financial and operational costs of these failures continue to climb sharply.
Critical Staffing Shortages and Sustainability Progress
The industry talent drought is worsening. More than half of all respondents in 2026 report difficulties finding qualified candidates for open positions, while staff turnover remains a persistent problem — with staff often lured away by other data center companies.
On the environmental front, corporate accountability is rebounding. The share of organizations actively collecting sustainability metrics returned to a gradual upward trend in 2026. Progress is particularly notable in resource tracking, with more than half of all operators now recording their water consumption. But tracking of carbon emissions remains a minority activity.
Methodology: Uptime conducted the survey online and via email and collected responses from more than 800 data center owners and operators. Nearly one in four respondents work for professional IT/data center service providers — that is, staff with operational or executive responsibilities for a third-party data center, such as those offering colocation, wholesale, software, or cloud computing services. The survey participants represent a wide range of industry verticals in multiple countries. More than half (52%) are located in North America and Europe.
