Reliability: It’s not great

Growing pains are never fun. It doesn't mention (at least that I read) if they're using HashiCorp Open Source or Enterprise. Open Source is great and I owe my career to it but they might be hitting the scale when the Enterprise features and support start to be worth the price.

I've only used Fly.io for a personal app but I think it's a great option so I hope they keep growing.
