Reliability: It’s not great

Fundamentally I think some of the problems come down to the difference between what Fly set out to build and what the market currently want.

Fly (to my understanding) at its core is about edge compute. That is where they started and what the team are most excited about developing. It's a brilliant idea, they have the skills and expertise. They are going to be successful at it.

However, at the same time the market is looking for a successor to Heroku. A zero dev ops PAAS with instant deployment, dirt simple managed Postgres, generous free level of service, lower cost as you scale, and a few regions around the world. That isn't what Fly set out to do... exactly, but is sort of the market they find themselves in when Heroku then basically told its low value customers to go away.

It's that slight miss alignment of strategy and market fit that results in maybe decisions being made that benefit the original vision, but not necessarily the immediate influx of customers.

I don't envy the stress the Fly team are under, but what an exciting set of problems they are trying to solve, I do envy that!

The CloudFlare folks wrote a good blog post on how they are seeing their customers use Edge compute — latency is far down on the list: https://blog.cloudflare.com/cloudflare-workers-serverless-we...

The US CLOUD Act means a EU customer cannot use a US cloud provider to host PII, even if the server itself is physically in the EU, because US law will still compel the provider to yield the data to US authorities. The European Commission is trying to paper over the cracks with a fig leaf of judicial review, but it's only a matter of time until a Schrems III decision from the CJEU invalidates that polite fiction.

You're assuming that the US doesn't respond to political pressure and come up with an agreement with the EC to enable the flows. The wiretap act already goes beyond the fourth amendment in protection.
