How to protect the site from API crashes?

Question

Watching the consequences of today's disconnection of Google on the Internet, I thought about how to prevent this in the future. This might be a dumb question, but is there a good way to enable external APIs (like Google AJAX libraries) so that if the API is not available, the inclusive page can still remain without soldiers? Is it a bad idea to use libraries hosted on an external server in general?

Answer 1

You cannot use a script tag to load cross-domain JavasScript files (this will result in a timeout if it drops). However, in your code, check that the API objects are null to avoid errors:

eg. instead:

<script type="text/javascript">
  google.load("maps", "2");
  // Use Maps API
</script>

:

<script type="text/javascript">
  if(google != null)
  {
    google.load("maps", "2");
    // Use Maps API
  }
  else
  {
    // Fallback
  }
</script>
