+# Cloud Datacenter Locations
+
+This dataset tracks the locations of datacenters operated by large cloud providers (e.g. AWS, Azure, GCP), each cloud provider has their own json file.
+It based on my research collected from publicly available information.
+
+## Accuracy of locations
+
+Cloud providers will rarely state the exact locations of their datacenters.
+They provide **region** or **zone** as options while procuring their services.
+These refer to a geographic area where they operate 1 or more actual physical datacenter(s).
+The granularity of each entry's known location is recorded explicitly (see `providerScope` and `geoPrecision` below).
+
+## Coordinates
+
+Coordinates of `geoLonLat` are found by entering the `location` string (the city or state named on the provider's own documentation page) into [OpenStreetMap Nominatim](https://nominatim.openstreetmap.org/), after coordinates are rounded to 3 decimal places.
+
+## Data model
+
+| Field | Description |
+| --- | --- |
+| `adm1` | ISO 3166-2 subdivision code (ADM1, e.g. `US-VA`). Omitted when the provider does not name a subdivision. |
+| `code` | The provider's official datacenter reference code. |
+| `country` | ISO 3166-1 alpha-2 country code (ADM0). |
+| `displayName` | Official long name from the provider's page. |
+| `geoLonLat` | `[longitude, latitude]`, geocoded from `location`, rounded to 3 decimal points. |
+| `geoPrecision` | Derived from the granularity of the official `location` string. Options: `country`, `state`, `city`, or `district`.  |
+| `location` | Official city/state string from the provider's page (used for geocoding). |
+| `provider` | `aws` \| `azure` \| `gcp`. |
+| `providerScope` | The provider's term for this code's level: `region` or `zone`. |
+| `source` | Full URL of the official page this entry was sourced from. |
+| `sourceChecked` | Date the source URL was verified (e.g. `2026-07-03`). |
+
+### Additional fields
+
+| Field | Description |
+| `zoneCount` | **AWS only.** Number of Availability Zones (AZs) in the region. |
+| `zones` | **GCP only, region-level entries.** Named zone codes (e.g. `us-central1-a`). |
