When Microsoft or Google CDN fails, what should u do?

Let me tell you one thing, an outage in CDN is very rare. But just in case you don’t want to take a risk, go ahead with this fallback mechanism, as suggested by Scott Guru.

<script type=”text/javascript” src=”http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.min.js”></script&gt;

<script type=”text/javascript”>

if (typeof jQuery == ‘undefined’)

{

document.write(unescape(“%3Cscript src=’/Scripts/jquery-1.4.2.min.js’ type=’text/javascript’%3E%3C/script%3E”));

}

</script>

<script src=”http://ajax.microsoft.com/ajax/3.5/MicrosoftAjax.js&#8221; type=”text/javascript”></script>

<script src=”http://ajax.microsoft.com/ajax/mvc/1.0/MicrosoftMvcAjax.js&#8221; type=”text/javascript”></script>

<script type=”text/javascript”>

if (typeof Sys == ‘undefined’)

{

document.write(unescape(“%3Cscript src=’/Scripts/MicrosoftAjax.js’ type=’text/javascript’%3E%3C/script%3E”));

document.write(unescape(“%3Cscript src=’/Scripts/MicrosoftMvcAjax.js’ type=’text/javascript’%3E%3C/script%3E”));

}

</script>

Use it for any CDN’s.

Let your mind be at peace.. 🙂
