This is one of the reasons I've been reluctant to start using a hosting provider (in addition to social engineering, it's always possible that their infrastructure gets compromised). Their problems become my problems. And on the other hand, some of the big ones are also prone to arbitrarily blocking you for random reasons, just like Google. Didn't take long for Hetzner to block me. I still host my mail at home and am my own registrar. There are still human elements of course but I've minimized them to the extent that is currently feasible.
