OP may have a different answer, but the Internet Archive[0] and the /r/DataHoarder[1] communities are really obsessed with digital archival and preservation. The latter has gone to great lengths to, well, hoard anything and everything imaginable that they can.

Doesn’t the Internet Archive have a collection of websites they backed up just before they went down? Do they plan on backing up Soup.io? Do they even know about it?
