Maybe I've just had bad luck, but since I started hosting my own websites back around 2005 or so, my servers have always been attacked basically from the moment they come online. Even more so when you attach any sort of DNS name to it, especially when you use TLS and the certificates, guessing because they end up in a big index that is easily accessible (the "transparency logs"). Once you start sharing your website, it again triggers an avalanche of bad traffic, and the final boss is when you piss of some organization and (I'm assuming) they hire some bad actor to try to make you offline.
Dealing with crawlers, bot nets, automation gone wrong, pissed of humans and so on have been almost a yearly thing for me since I started deploying stuff to the public internet. But again, maybe I've had bad luck? Hosted stuff across wide range of providers, and seems to happen across all of them.
