  ## <a id="unsharing"></a> Unsharing a Service Instance
  
  <p class="note warning"><strong>WARNING:</strong> Unsharing a service instance 
  automatically deletes all bindings to apps in the spaces it was shared into.
  This may cause apps to fail. Before unsharing a service instance,
  run the <code>cf service SERVICE-INSTANCE</code> command to see how many bindings exist in the spaces the service instance is shared into.</p>
