+h3. Federated downloads
+
+If your cluster is "configured to be part of a federation":{{site.baseurl}}/admin/federation.html you can also download collections hosted on other clusters (with appropriate permissions).
+
+If you request a collection by portable data hash, it will first search the home cluster, then search federated clusters.
+
+You may also request a collection by UUID. In this case, it will contact the cluster named in the UUID prefix (in this example, @qr1hi@).
