Fly has a form of auto-scaling. You have to provision the max amount of machines then you configure them to auto-sleep. It's possible that the creator didn't anticipate this much traffic or didn't want to pre-pay for all those sleeping machines.

That's just pre-provisioning by another name, auto-scaling implies on-the-fly provisioning

E: I can't even load the fly.dev website, it keeps timing out. I guess they forgot to pre-provision/under-provisioned it

No, they have auto-scaling as well. Not sure what GP was talking about: https://fly.io/docs/reference/autoscaling/

However, it's understandable that some people wouldn't necessarily want to pay for high amounts of max machines.

Apparently it doesn't auto-scale automatically either, you have to opt into it.
