Do you serve jQuery to your users from Google on a public websites ?

Answer 1

Pros:

• There is a very high chance that your site users will already have the file cached on their computer which speeds up load time.

Cons:

• If Google is down, your site won't work.
• If you need to use your site (say on an intranet, or local computer) without internet access, you can't.

Google Uptime: I saw it argued here before on another question that Google will have better uptime than your server. But funny enough, another commenter brought up this point: When will it ever matter that your JS has better uptime than the rest of your site.

Answer 2

pros will be that it will be cached for uses that visited another site that also uses Google hosted jQuery

con: if Google is down then your jQuery is unavailable
