+
+Regions available for a cloud project.
+
+The `ovh_cloud_region` table can be used to query information about regions and **you must specify which cloud project** in the where or join clause (`where project_id=`, `join ovh_cloud_project on id=`).
+
+## Examples
+
+### List regions of a cloud project
+
+```sql
+select
+  name,
+  type,
+  status
+from
+  ovh_cloud_region
+where
+  project_id='27c5a6d3dfez87893jfd88fdsfmvnqb8'
+```
+
+### List regions not UP
+
+```sql
+select
+  name
+from
+  ovh_cloud_postgres
+where
+  project_id='27c5a6d3dfez87893jfd88fdsfmvnqb8'
+  and status!='UP'
+```
+
+### Get specific region
+
+```sql
+select
+  name,
+  type,
+  status
+from
+  ovh_cloud_region
+where
+  project_id='27c5a6d3dfez87893jfd88fdsfmvnqb8'
