title: Youtube Quota Exceeded Exception when it's actually not
body: <p>We're using the youtube data api v3 and have been for quite some time without any problems. Recently, we've been getting this 403 exception:</p>
  
  <pre><code>The request cannot be completed because you have exceeded your &lt;a href="/youtube/v3/getting-started#quota"&gt;quota&lt;/a&gt;.
  </code></pre>
  
  <p>In the google developer's console, it says that we are still under the quota (currently it states "units/day 163,817 of 50,000,000").</p>
  
  <p>Am I missing something about how quotas work?</p>
