Maybe if you switched to a high-end hosting provider like AWS.... oh wait...
Yes, but with AWS you have a lot of power at your direct command and you can structure your systems to assume the sort of risk you want, from "availability zone in this region goes down, site is dead until it's fixed" to "this thing will keep running unless every Amazon region around the world has died".
But of course, you have to be able to do that setup, if it's not your day job, better to leave somebody else to do it for you, if nothing else that there's a lot of assholes and botnets out there who will stop at nothing to try and kill your site/server/network. Some are smarter than others.
Not all of them are as kind as one I caught today who kindly announced it's UserAgent as "WebFuck V2.1 T0PHackTeam
www.t0p.xyz" as it searched through some sites for exploits.
