Lately, I've come across many articles which suggest that you host your own static assets (especially fonts and css) instead of using a worldwide CDN like CDNJS. The argument they cite is that your own site will be much faster than CDN, so the assets will load faster.

But my argument is that if I use a popular library like jquery or bootstrap, chances are that they've already been downloaded to the user's local machine through a CDN (because dozens of other websites the user may have visited use CDNs). So, the network cost is zero! But if I host a jquery.min.js or bootstrap.min.css specifically on my server, it'll be an additional toll on network resources, isn't it?

So, I think that hosting your own asset is an anti-pattern, what do you think?
