Info on free CDN

I would recommend taking a look at KeyCDN. They aren’t free but lowest global price at $0.04/GB, 20+ POPs, free origin shield, free secure token and HTTP/2 support. Do you know how much bandwidth your site uses? If so, you can do the math and see how cheap it is.

KeyCDN also developed and maintains this free WordPress CDN plugin you can use. Makes deploying the CDN a breeze.
