Its not actually an article, its a slide deck with a bunch of marketing on it. And I did read it. These are unsubstantiated numbers. 10% of total daily HTTP requests? Where is the total daily number of HTTP requests on the internet published? Cisco's VNI approximates bandwidth but I have never seen any number for the total HTTP requests on the internet.

I am aware that Cloudflare is a CDN, most CDNs are substantial internet companies. However I've worked at a couple of CDNs and they all throw a lot of marketing numbers around.

If memory serves, the 10% isn't based on some kind of global estimate of HTTP traffic. It's based on what percentage of active IP-space they see on a daily basis.

Now that's a marketing metric :)
