We at some point, we where retrieving some javascript (jQuery) and fonts dependencies from a CDN. At the end, we need that change and include all in out web application as we saw all kind of problems... Like that someone trying to use behind a intranet or not working fine when it's accessed a develop version behind a weird VPN. Or that funny moment when a CDN get down and simultaneously a lot of our webs get half broken.
