Thanks for sharing your experience with contabo. Do you have any idea how much it would cost to run one on other services, say Amazon?

AWS has a lot of options, possibly there is a cheap way that I'm not aware of, but if you are looking into a their managed Postgres options that's really expensive. A dedicated root-server for ~50$ per month is probably your best option for a very reliable Hivemind.

Cool. Thanks for the info :)
