title: Why so many time out from Google related URLs from time to time?
body: <p>My website uses Google Ads Conversion and Google Analystics. From time to time, I will see Chrome reports errors in accessing Google related URLs, such as</p>
  <pre><code>GET https://www.googleadservices.com/pagead/conversion_async.js net::ERR_TIMED_OUT
  </code></pre>
  <p>A screenshot is put below:
  <a href="https://i.stack.imgur.com/awXaB.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/awXaB.jpg" alt="enter image description here" /></a></p>
  <p>THe error is generated from Google Tag Manager with the following URL:</p>
  <pre><code>https://www.googletagmanager.com/gtag/js?id=AW-1071615551&amp;l=dataLayer&amp;cx=c
  </code></pre>
  <p>I am curious why this will occur so frequently since Google has the best server and network connection in the world?</p>
  <p>I have seen some report indicating Google Server is the best, for example:</p>
  <ol>
  <li>Google CDN is the 2nd fast, see <a href="https://www.cdnperf.com/" rel="nofollow noreferrer">https://www.cdnperf.com/</a></li>
  </ol>
  <p>Another report is not in English so I do not put it here.</p>
