Datacenter buildout activity issue for June 29, 2026

For the satellite window ending 2026-06-29, 6 of 50 assessable announced datacenter sites showed active earthworks; the fleet index was 12.0 out of 100.

Against the prior weekly issue, the index moved -0.8 points and the count of sites classified as active earthworks moved +0. The index measures rising exposed soil across a fixed site universe. It is evidence of observed surface change around datacenter sites, not evidence of project capacity, completion, financing, or intent.

How the observed fleet changed

In this issue, 6 of 50 assessable sites cleared the active-earthworks threshold; 35 were stable and 9 showed falling bare-soil momentum. 7 sites were excluded from classification because the usable-scene floor was not met. These categories are mutually exclusive for the issue and sum to the assessable-plus-insufficient universe shown above.

The public page intentionally stops at fleet aggregates. Per-site signals and operator rollups are the paid deliverable; exposing them here would erase the product boundary. The aggregate remains useful for checking whether the tracked fleet accelerated, slowed, or became less observable without turning a single site's optical classification into a commercial claim.

Coverage and interpretation

The June 29, 2026 issue covers snapshots from 2026-06-09 through 2026-06-29. A site requires at least two usable scenes after cloud and valid-pixel filters. The denominator printed above is therefore assessable sites, not every announcement in the universe. A site absent from the active count may be stable, greening, cloud-obscured, already built, inactive, or moving in a way the optical measure cannot see. Static high bare soil is descriptive only; it never qualifies a desert site as active.

Method, source, and content seal

The June 29, 2026 issue uses Copernicus Sentinel-2 L2A imagery discovered through Element 84 Earth Search. Each site's announcement provenance is linked in the active table. The method measures the change in exposed bare soil between usable observations. The active threshold is frozen at five percentage points so ordinary pixel noise does not become a signal.

The June 29, 2026 artifact reproduced its declared SHA-256 seal before this page rendered. The seal binds the method version, thresholds, complete panel, state counts, headline, operator rollups, and site rows.
