Waiting reply from ajax.googleapis.com

I have added jQuery to my webiste from google. The awful part is the completly slowness of google server. Sometime my website stops while trying to loading jquery from googleapis:

<script src="http://ajax.开发者_运维百科googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>

Can i do something? It's better to load jquery from other servers ? (maybe mine?) When the "waiting reply from ajax.google" appears i can stay 30min waiting and nothing happens, I have to reload the page to show it

In my case, I found its better to NOT use external CDN.

1. You don't have power over it, Google can stop serving a version of jQuery
2. On page load, it means 1 HTTP request to 1 different host (not good since browser does parallel queries)
3. Most of the time you use a minifier so you can include the jQuery lib in your big minified file to reduce HTTP requests

And I found that Google CDN is very slow... I constantly get "Waiting for ajax.google....."

I've never had a problem with it.

On a side note, you should always use the full version of jquery. e.g. -

http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js

You lose the caching benefits if you use simply 1.4 or 1.5.

Here's a pretty good article about why you should use the Google CDN:

It is better to use google CDN then loading from your server. Most of the users already have jQuery from google cached and don't even have to load it.

You can also try loading jQuery from microsoft CDN at

http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.5.1.min.js

You can also have jQuery load from your server in case it wasn't loaded from google. You do that by writing

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>
<script type="text/javascript">
if (typeof jQuery == 'undefined')
{
    document.write(unescape("%3Cscript src='/jquery-1.5.1.min.js' type='text/javascript'%3E%3C/script%3E"));
}
</script>

FWIW I was having atrocious load times from chrome (2m+) with a codebase then I discovered it was using:

https://ajax.googleapis.com/...        # slow

Switching away from https in the code fixed it, now it's lightning fast (as long as you're online):

http://ajax.googleapis.com/...         # fast

Sorry OP, I see you're not using https but perhaps this will help others. But wrt the original thread I prefer to have control and be able to do offline development, and if you put static assets on a good CDN it's a much of a muchness whether you use Google's or your own. But if you want something fast for others without hiring a CDN it's a tradeoff, as others have said, between relying on Google's CDNs (which could go away at some point, though not likely soon) or setting up your own or giving your users a slower load time.

I know it has been a while and this is an old issue.

Similar things happened to me and I can assure you it s not because of google's cdn. In my case it only happens for in the Google Chrome not Firefox or Internet Explorer (not event IE can you believe it) so I decided to remove html parts one by one and turns out it s space entities in the html like tons of   some how Chrome cannot handle them correctly (tries to replace them all I think) and this cause the problem and always show waiting message.

Basically the content guy used these entities to for correcting layout of some data. I used a simple table instead and fixed my problem.

This one about one year ago and I also sent a bug report to Google using Chrome. well I am not sure it has been fixed or not.

Hope this helps someone.
