The industry-average PUE decreases slowly, with efficient new data centers offset by legacy facilities. Weighting the average by IT capacity instead reveals a faster pace of efficiency gains from larger new builds.

The Uptime Institute Global Data Center Survey, now in its 16th year, highlights the practices, perceptions, intentions and experiences of data center owners and operators across resiliency, sustainability, efficiency, staffing, cloud and AI.

The early years of scale DLC deployment came with complexities in system design, coolant chemistry, resiliency design and maintenance practices. Operator experiences suggest consensus is beginning to form, if imperfectly.

While water cold plates continue to dominate current liquid-cooling adoption, the industry has also turned its attention to different approaches, with two-phase cold plates in particular becoming a promising alternative.

DLC was developed to handle high heat loads from densified IT. True mainstream DLC adoption remains elusive; it still awaits design refinements to address outstanding operational issues for mission-critical applications.

DLC introduces challenges at all levels of data center commissioning. Some end users accept CDUs without factory witness testing — a significant departure from the conventional commissioning script

Uptime's 2025 cooling survey found that fewer respondents cited sustainability as a primary driver for direct liquid cooling (DLC). Gradual advancement of DLC plans may be refining operator understanding of its incentives.

Large-scale AI training is an application of supercomputing. Supercomputing experts at the Yotta 2025 conference agree that operators need to optimize AI training efficiency and develop metrics to account for utilized power.

Liquid-cooled colocation capacity remains niche, but demand is likely to grow. Colocation providers planning capacity for DLC need to address novel questions about individual tenant needs, operations and SLAs.

Water cold plates still lead DLC adoption - but more enterprise operators are considering dielectric cold plates than last year. The next DLC adopters may be amenable to multiple technologies, while remaining cautious about leak risks.

The 15th edition of the Uptime Institute Global Data Center Survey highlights the experiences and strategies of data center owners and operators in the areas of resiliency, sustainability, efficiency, staffing, cloud and AI.

Direct liquid cooling challenges the common "line of demarcation" for responsibilities between facilities and IT teams. Operators lack a consensus on a single replacement model-and this fragmentation may persist for several years.

How far can we go with air? Uptime experts discuss and answer questions on cooling strategies and debate the challenges and trade-offs with efficiency and costs.Please watch this latest entry in the Uptime Intelligence Client Webinar series. The…
