Ideally, we'd all be using very good and competent hosting companies, but they're not ideal for free/low revenue projects. It's better to have some down time than having to shut down the service because you can't afford to keep it running.

I think that in both cases here (OpenFreeMap and wplace), Hetzner/OVH/Scaleway is the way to go. Depending on what we're doing, the cost savings can even allow us to have redundancy at another cheap provider just in case something goes wrong.
