If you’re using jQuery on your site (or your client’s), you probably have this line at the very bottom of your pages:
It’s a good way for avoiding an extra HTTP request if the visitor has the script already loaded in his browser cache. However, it’s relying on a remote source, which means that you have no control over it. So if the file is removed or the link breaks for any reason, your site (or your client’s) won’t be able to load it.
Yeah! jQuery’s site was broken, and it was for at leat 10 minutes. So a lot of websites around the globe could be looking weird at a time. A funny idea, but not so funny if your site is jQuery dependent.
