I couldn't understand that site plus apart from bitmain, I am not going to any coinflare-slowed website.
Cloudflare is a great service. Not only does it cache websites locally for everyone in the world (rather than 400ms ping to Chinese servers), it provides DDOS protection. Bitmain and several other Bitcoin services are under attack because they did not pay ransoms. On top of all that, Cloudflare does it for FREE.
Unfortunately Cloudflare is useless for protecting a mining pool as they don't support custom protocol's such as stratum.
