@ml well, I didn't include Hetzner because they shut down an account without prior notice, no chance for downloading a backup, nothing. And, yet, they sent an invoice (later waived).
Their servers are great indeed, but the management is in the other end of the spectrum.
As for Contabo, I didn't include it at first because of some love and hate people seems to have about them. But I guess they're as good as OVH.
