The blog link was down for a couple of hours some days ago, it's back online since then. I know Funkwhale very well and I used to run my instance before. But there are too many gaps that left me unsatisfied - ActivityPub integration is very minimal and only limited to collections, implementation of the Subsonic API has also many gaps, no streaming over custom HTTP mountpoints or Icecast, no listening stats, no support for external libraries/sources, and most importantly no built-in support for payments (which is the reason why most of the musicians who try to make a living out of it are still on a bad platform like Bandcamp).
