Why is jquery not loading from googleapis?

Question

Google

I include jquery at the top of the page, everything works fine.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.3/jquery.min.js"></script>

Only periodically the error takes off
Can't find variable: $
It turns out in some cases jquery is not loaded. Most often this happens in Firefox 43.0. What is done wrong?

UPD:
The code is used internally

$(document)
    .ready(function() {})

Answer 1

Fix uploading to (this solves problems with the locale):
It also happens if Jquery did not have time to load. Wrap code in

$(document).ready(function() {
 Ваш код
});

Answer 2

You open this url from the script src and save it to where your project is and everything
https://ajax.googleapis.com/ajax/libs/jquery/2.2.3...
In general, we often have google and everything that is connected through it is not works, and this is the google youtube toster itself and any resources that have a script connected from them
