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.
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.
