Sometimes bad people fill up the internet pipes to stop people using a website. Cloudflare has big internet pipes and lets people use them for free to stop people filling up your own pipes and taking it down. Because of this lots of big websites and services use Cloudflare's pipes. Big cloud companies (like Cloudflare) have lots of very complicated services and sometimes things go wrong in complex systems and everything stops working. When this happens with Cloudflare people notice because its a single point of failure.
