710 of 4,257 facility records carry an operational measure

4,257 facility records are individually browsable here, of which 710 carry an operational measure — power, GPU or FLOP capacity, or a substantive description. The other 3,547 establish that a site exists and stop there. Which of the two a record is depends almost entirely on the catalogue it arrived in, not on the site.

What a record can tell you, by the catalogue it came from. Each band is one catalogue: its length is that catalogue’s share of the largest one’s row count, and the inked run inside it is the rows carrying at least one operational measure — power, GPU or FLOP capacity, or a substantive description. Nothing here is schematic; both lengths are measured proportions of counts printed beside them. No share-of-megawatts is drawn, and its absence is deliberate — every megawatt-bearing row satisfies the measured predicate by construction, so a capacity share would be a tautology rather than a finding. Counts are the full anon-visible set, 4,257 rows, read 20 August 2026. The smallest catalogues are folded into one band rather than dropped — its run is hatched because it averages catalogues of both kinds — and each named catalogue’s key opens the register below scoped to its rows.

The bands separate rather than shade. Epoch AI Frontier Data Centers runs 91.4% measured across 70 records; OpenStreetMap runs 0.0% across 231. No single catalogue sits in between — the hatched band does, but it is the fold of 43 smaller catalogues and prints mid-scale only because it averages the two kinds. The separation exists because the two kinds of catalogue are doing different jobs: one is a research dataset built by measuring sites, the other is an infrastructure registry built by recording that they exist. Both are honest; only the aggregate that hides the difference is not. Any band’s key below opens the register scoped to that catalogue’s rows.

This is why the register opens on the measured cohort and says so, rather than showing 4,257 rows of which most cannot answer the question a reader arrived with. The positional records are not filler — a site that exists is a real fact, and for a governance reader tracing where capacity might appear it is often the fact that matters. But it is a different fact from a megawatt figure, and a register that prints them in one undifferentiated count is making a uniformity claim its substrate does not support.

Two counts appear on this page and they are not the same quantity. The masthead stamps 4,573 tracked records — the full corpus across 110 countries, the figure used site-wide. The register and the plate count the 4,257 that are individually browsable; the 316 in between are rows a licensing term keeps from being served as their own record. They inform aggregates and they are not hidden, but they cannot be opened, so a figure about what a reader can inspect must not count them. The same universe is plotted in space on the map, rolled up by jurisdiction on Countries, and the organisations that own and operate these sites are in the company register.

Every record matching the current filters — all 1 — carries an operational measure.
