title: Google managed certificate
body: <p>Do I need apply Google managed certificate for each prefix of domain as in the following?</p>
  <pre><code>socket.flytime.io
  api.flytime.io
  flytime.io
  www.flytime.io
  </code></pre>
  <p>As it seems like certificate for <code>flytime.io</code> can't be used for <code>api.flytime.io</code>.</p>
  <p>Also, does api.flytime.io belong to domain of flytime.io, or are they totally separated domains?</p>
