CloudFlare is a "middle" server to mainly defend your web server from ddos (though it has features to speed up your website by having CDN, etc)
It happened to everyone that was accessing the website because the BC server was down, but CloudFlare cached it so you can access it while the website is down)
It is not a program, but a server which is between Bleeping Computer and your pc (bleeping computer chose this protect their server and to speed it up so you don't have to worry)
You can sign up here if you want to protect your website
They have free protection (basic), Pro, and Business (more information about each plan's features is here)
Its up to you which one to choose, but first try with their basic protection which is free
