They made a private Calckey (now called FireFish) instance a while ago for Lemmy updates - whenever the instance would go down, there would be a post on the FMHY Calckey account. You can read about what happened here and what they are planning on doing about it: very.bignutty.xyz/notes/9hg4dquksvbha67h
Best case scenario is that they can get the fmhy.ml domain back, only if the Mali government opens registrations again. It looks as though they will be starting from scratch with fmhy.net instead.
