I guess I don't understand this, I thought cloudflare was just a cdn and put up static versions of sites when sites were under DDOS (along with DDOS mitigation techniques), I didn't think they hosted sites themselves? am I missing the point or do they host or act as an intermediary for some websites or something similar?
