How are POST requests replayed into different regions? Does your edge proxy hold the whole POST requests (body and all?) just in case it needs to be replayed?
Fly.io and the Postgres service look great. Do you have a roadmap for future regions? (I'd personally love to see Korea.) If I may ask, do you use major cloud services or run your own machines, and how easy or hard is it for Fly.io to add new regions?
We don't have a firm roadmap for future regions, but Seoul is high up on my wish list.
Our infrastructure is all dedicated hosts, mostly running in Equinix facilities (we buy a lot of servers from what used to be packet.com).
New regions are hard in one particular way. Since we accept anycast traffic, ever new region has to be anycast-able for us. We outsource anycast management so we're kind of stuck waiting on other providers to opt in to a region.
When we get to a scale where we can manage our own anycast and decide we want to, we will be able to ship new regions relatively quickly. Some places are harder to get servers to than others, but we don't actually need a very large footprint to get started.

It does, and we need to update our docs with this.
We buffer up to 1mb of request data to be possibly replayed. We can set that arbitrarily high, it just seemed like a reasonable starting point.
Cool, makes sense. Thanks for taking the time to reply! Really big fan of fly, run a few apps on it now and the experience has been fantastic.
