From the post, FaunaDB initially had several issues, which they've generally resolved. Jepsen is open source, so I'm curious why a database company wouldn't run Jepsen internally, work out as many problems as they can, and then engage aphyr in order to get the official thumbs up. Given how important data integrity is, I would assume that any database company would be running Jepsen (or something equivalent) regularly in-house. If they are doing that, then how is it that aphyr finds so many previously unknown issues? And if they aren't running Jepsen in-house, why not?
