We need less reliable systems, not more.
I mean, that's why a mobile phone is being used, no? Because otherwise, a Raspberry Pi would suffice and would be cheaper and more reliable.

Neither of these has happened to me. If they did, the uptime of my personal blog would be a much lower priority than fixing that problem. It's a blog, not a business.
