title: After months of 100% stability, today I get 403 Error on google maps services
body: <p>I was just wondering if someone could shed some light on why I am seeing 403 Forbidden errors for my google maps services.</p>
  
  <p>I had been loading the maps api as such:</p>
  
  <pre><code>&lt;script type="text/javascript" src="//maps.googleapis.com/maps/api/js?libraries=places&amp;amp;sensor=false"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>And then using both the geocoding and autocomplete libraries to turn user searches into co-ordinates to display on a map on my search results.</p>
  
  <p>This was working perfectly (for months) until yesterday, when I started seeing 403 Errors whenever the Autocomplete service was accessed.</p>
  
  <p>I am 100% confident I wasn't reaching the 25k per day limit on queries, and I made no code changes on my side.</p>
  
  <p>I have now added in an API key to my script load, and the problem dissapeared, but I want to be sure this doesn't happen again. Location based search is a main feature on our site, and if it breaks, we lose customers.</p>
  
  <p>Does anyone have any insight as to why this may have happened? </p>
  
  <p>And under what circumstances can it happen again?</p>
