You know what sucks? Getting your VPS shut off or account suspended. All your data gone in an instant, not recoverable. You don't have access to the metal, and the metal no longer has access to you.
Hetzner is known for randomly boinking accounts. You update billing info? Whoops maybe shutoff. You login via a VPN, account disabled. Just randomly for no reason, account locked and VPS down.
You have basically zero recourse. Their support staff suck and the immediate reaction is suspend and delete. NEVER use them for anything you don't consider temporary.
