# Datacenter Atlas: curated sample (data version 26.08-c2)

200 facilities in 61 countries, out of 8460 in the full inventory.
Curated for completeness (mostly grade A): **not statistically representative**.
Source release 26.08 (2026-07-21), correction layer applied 2026-09-25. Cite the data version 26.08-c2.
The data version changes whenever the correction layer changes. Derived columns follow their own index version:
derived_sfi = social friction index v0.3 (method of 2026-10-12),
derived_wsi = water stress index v0.2 (method of 2026-09-24).

- `asset_type_reason`
- `lat`
- `lon`
- `geo_precision`
- `geo_flag`
- `address`
- `city`
- `region_state`
- `country_name`
- `country_iso2`
- `continent`
- `it_load_mw`
- `mw_shared`
- `mw_campus_n`
- `mw_campus_id`
- `total_power_mw`
- `pue`

- `carrier_count`
- `website`
- `sources`
- `source_urls`
- `last_verified`
- `dqs`
- `dqs_grade`

Provenance: one source per value (empty when the source gave no link):
- `src_name`
- `src_operator`
- `src_location`
- `src_address`
- `src_city`
- `src_region_state`
- `src_country`
- `src_it_load_mw`
- `src_total_power_mw`
- `src_pue`
- `src_gross_floor_area_sqm`
- `src_tier`
- `src_certifications`
- `src_cooling_type`
- `src_status`
- `src_commissioned_year`

Derived indicators (computed from open datasets, describe the location, see https://www.datacenter-atlas.com/methodology/indicators):
- `derived_wsi`
- `derived_sfi`
- `derived_bws`
- `derived_bws50`
- `derived_fc18_h`
- `derived_cdd`
- `derived_hot_days`
- `derived_pop5k`
- `derived_sub_km`

`dc_uid` is the permanent id (`id` in the site's APIs). Group by `mw_campus_id` to count a shared campus IT-load figure once.

## Location precision
`geo_precision`: `building` = mapped footprint, `point` = a point at the site,
`municipality` = the operator does not publish the address and the point marks the town (rule GEO-2);
derived columns are left empty for those rows.
