Thanks a lot for your input. So you'll be switching from Hetzner to privex? Or from both to privex?
I decided that a VPS is enough for the start. I registered with Hetzner, they wanted 20 € upfront to show I am serious, I waited until another morning. Then, when I tried to log in, the account was disabled. Supposedly it's a common practice at Hetzner. I sent them an email with the complaint. Well, I didn't wait for their support to wake up - they didn't answer yet. End of story for me!
Good luck with privex.
I'll just be taking one of my hive engine witness nodes(either main or backup depending on things go) to privex.
