Does anyone know if Google\'s CDN for jQuery is available in China?
http://code.google.com/apis/ajaxlibs/
I might have a project where I\'ll need to support
If there's a chance the Google CDN would be blocked in China, just go ahead and use a local version of jQuery on your own site.
There are other advantages to not relying on Google too - if you're writing a lot of jQuery code you could compress jQuery and your app all in one file and save some HTTP requests.
Google's Closure Compiler may be able to save you a lot of bytes by removing functions you're not using - although last time I checked it didn't do this for jQuery very well.
