Yeah I'm operating on a shoestring but tbh servers are super-reliable as is Postgres. What even is "production grade"? Read replicas, point-in-time restores etc? For a product that is ~$1000 ARR I think I can live with a bit of risk (I do regular backups of course and have a restore process). Maybe it will bite me in the ass, but I'll risk it :)
Happily using Cloud66 but a strong recommendation for Northflank here. I already had a running cluster there and migrating a very complex Heroku app over only took 20 minutes today. (Would have been 5 if I hadn't screwed up .gitignore...)

So your statement is not true. Because Switzerland was not prepared, they had to resort to other means.
