Ubuntu server suddenly replaced with Windows Server 2012

About a few hours ago my server stopped responding, I couldn't ssh.

I went into Hetzner console and opened console from there, and found that my Ubuntu 24 server now says Windows Server 2012.

I'm quite confused, it seems like either this was a royal fuckup by Hetzner, or my system was compromised. I'm quite secure in access, and the machine is only accessible by ssh key (not password).

I checked Hetzner console and there were no activities other than mine (eg Console access). So if it was a compromise the hacker streamed a Windows image to replace the file system.

Anyone have any clue what might be going on?
