> I find that most cloud providers really earn their money from transit/bandwidth costs, whilst oversubscribing their compute resources to then sell them at a discount - does this not make the WireGuard proxying prohibitively expensive?

Oh, my VPSes don't have data transfer costs as a dynamic component (Time4VPS, linked above). I just pay a fixed fee for a given amount of bandwidth and if I exceed it, then the speed is reduced for that VPS until the end of the month.

Here's the relevant bit from their FAQ:

> We reduce your VPS server’s port speed 10 times until the new month starts. No worries, we won’t charge any extra fees or suspend your services.

That said, they're definitely not the only platform that does something similar, many other VPS providers also have certain amount of data transfer included, Hetzner and Contabo included.

I actually have to say that Hetzner is perhaps the best billing wise, because if you just need a VPS for an hour or something, you can also order it for that amount of time, instead of a full month like with many other providers.

Either way, in my case I don't need to worry about the bandwidth too much, because nothing that I want to expose publicly is that popular, at least from my homelab nodes - mostly test environments and such to show to friends/colleagues and so on. Most of the stuff that can generate a bit more traffic (for example, my blog) I host in the data center that gives me all my other VPSes as well, just to not overwhelm my residential connection.
