It was my home to my account. I didn’t catch any announcement it would be going down. 2 weeks ago the website started throwing errors (50* internal server errors) and since a week it is completely unreachable. There are still DNS records resolving the domain, but the site seems completely gone.
Yeah I've been against promoting smaller instances from the very beginning for this very reason.
If it's small and has been established for years? Go for it. If it's small and just popped up recently? It's a pretty big risk.
I like the idea of a federated network of lots of smallish instances. You're absolutely right, though, that some flux is to be expected, and evident.
