Uptime Institute Global Data Center Survey Results 2026 - 16th annual survey, published July 2026

Fetched 2026-10-04 (landing page). The Uptime Institute published its 16th annual Global Data Center Survey in July 2026. The landing page confirms the survey exists and is available as a downloadable executive summary, but the actual survey data (PUE figures, power density trends, tier distribution) is behind a download wall and was not accessible in this fetch. The page also references a July 2026 paper 'Energy Efficiency in Digital Infrastructure: Why It Matters, Why It's Hard, and How to Get It Right' which is similarly behind a download. The Uptime Institute is the standard bearer for datacenter tier certification (Tier I-IV) and their annual survey is the primary industry source for PUE averages, power density trends, and outage statistics. The existing repo record (pwr2-vantage-power-density) covers Vantage's power density tiers but not the industry-wide PUE data that this survey would contain. NEGATIVE: the specific PUE and power density figures from the 2026 survey could not be extracted from the landing page.
