Data Center and Web Infrastructure Statistics
Research updated for 2026
The physical and protocol layers of the web are measured less consistently than most people assume. There is no official registry of data centers, and protocol adoption is tracked by a handful of networks with their own vantage points.
These four pages cover what the infrastructure actually looks like, what it consumes, and which technical transitions are progressing against which ones have stalled.
How many data centers are there?
There is no official registry of data centers, so every count is an estimate from a commercial tracker. This covers the global and US totals, the hyperscale subset, and why the numbers disagree.
How much energy do data centers use?
Data center electricity demand sits behind most sustainability arguments about the web. This covers current consumption, the projections to 2030, and the water use that gets discussed far less often.
Green and sustainable web hosting statistics
Carbon estimates for web pages vary widely by methodology, and one of the most repeated claims about internet emissions is genuinely contested. This covers what the models say and where they disagree.
Web protocol adoption statistics - IPv6, HTTP/3 and TLS
Protocol adoption rarely follows the narrative written for it. This covers where IPv6, HTTP/3 and TLS actually stand, including the transition that stalled and the one that passed a milestone after eighteen years.
These pages describe infrastructure at industry scale. To price it rather than measure it, the cloud vs colocation vs on-prem TCO calculator compares renting against owning across a planning window, and the colocation cost calculator prices rack space and power directly. Return to all research.
