I played around with fly.io for a bit, it seems pretty interesting. It works pretty well too, I went through the setup for the DoH proxy and the latency I get is very similar to Cloudflare itself, so that's pretty awesome.

It seems that the autoscaling limits are only defined in the fly.toml with the soft and hard limits? It might be useful to make this easily visible under flyctl scale. Also if I delete the fly.toml, can I regenerate it easily?

As a sidenote, I was looking around for more information on the platform and looking at old hn posts. I know the company pivoted a couple of times, but all the old articles are 404ing because the blog url changed.
