New Post: Does SP Services have a public hosted library?

Hi Folks,

I found codes that uses google hosted libraries.

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

Does SP Services have public hosted libraries?

Does the use of Public hosted library pose a threat to a SharePoint Site's Security?
(I usually include the JQuery and SP Services library on a Document Library for that site since I dont have access to the Style Library.)
