On the Fireside Fedi interview with Jerry ( the admin of Infosec.Exchange Mastodon instance ) a scary truth was suddenly revealed ( on 34:11 ): Just to keep the instance up and running he needs to spend up to $5000 a month, pretty much out of his pocket. Donations to the instance barely cover any of that. And if he will ask people to pay to use it, they will, rightfully so, switch to a different instance.
Yes, the cheapest ones might have some risks, I mostly presented it as an example of what the opposite extremity looks like. There is a lot in-between, something a bit more expensive is even more guaranteed win. For example last time I used Hetzner, I had a server with 64gb RAM, 2TB SSD, and 16 cores Ryzen for something like €34/month. Hetzner support is very decent and they’re very well known, have decent reputation and been providing their services for a long time.
