Use Microsoft CDN for JQuery or Google CDN with fallback

When we develop modern websites it will become more frequent that we use some kind of javascript library. And as it is we should always use a CDN from Microsoft or Google when we use these libraries.

Here is a link,,  on why we should use it but in my case I thought I should share a fallback as well that are not that commonly used in projects.

<script src="//"></script>
  <script>window.jQuery||document.write('<script src="js/libs/jquery-1.5.1.min.js">\x3C/script>');</script>


These are the links to Microsoft CDN and Google CDN:

How often will that fallback be needed? :)

well... hopefully never but actually this happend the other day to a customer that could not use google domain and therefore could not use jquery libs. :)

So it is not like i think google will go down or microsoft :)
