What are you running on it is the only question which matters, obviously you dont want air traffic control to go down but some app… So what if it goes down? Backup is somewhere else if you even need it anyway. Github has uptime less than 90% according to this: https://mrshu.github.io/github-statuses/ . And the world keeps turning. Obviously we should strive for better, but also lets please not continue making this uptime fetish out of it, for vast majority of the apps it absolutely doesnt fucking matter.
