  -When you add an org to one isolation segment, it becomes the default isolation segment for that org unless another default is already set. This means that new spaces created within the org will be in its default isolation segment unless specified otherwise.
  +Only admins can add orgs to isolation segments.
   
   In the data field of the `curl` command, specify one or more orgs by GUID to add to the isolation segment. The following example adds two orgs to an isolation segment:
   <pre class="terminal">

  ### <a id="set_org_default_is"></a> Set a Default Isolation Segment for an Org
  
  If an org has resources in multiple isolation segments, one segment serves as the default, and new spaces created within the org will be in its default isolation segment unless specified otherwise.
  
  You set the default isolation segment for an org by sending a request to the endpoint for the organization, setting its `default_isolation_segment_guid` data property to the GUID of the new default isolation segment. For example:

  You add a space to an isolation segment by sending a request to the endpoint for the space, setting its `isolation_segment_guid` data property to the GUID of the new default isolation segment. For example:
