I'm more annoyed that I had to deal with the change. The migration took a couple hours and I'm still not sure if I configured it correctly to mirror the v1 setup I had.
They also changed regions during the migration. My db (hosted in a different app) was in LAX, but the new machines were in SEA.
With that said, our core systems are still on GCP and we use Fly exclusively for Next.js UIs so the comparison is to systems like Netlify and Vercel, both of which are far less reliable in our experience, and far costlier (Netlify is at the point of nickel and diming people).
