Terrible examples, Github and Google aren't just websites that one would place behind Cloudflare to try to improve their uptime (by caching, reducing load on the origin server, shielding from ddos attacks). They're their own big tech companies running complex services at a scale comparable to Cloudflare.
How? If Github is down how many people are affected? Google?

Yeah, and in the world with Cloudflare people don't care if Jim's Blog is down either. So Cloudflare doesn't make things worse.
