taskylizard quoted this post 8 hours ago, from nullishcat, which explains a bit more.

The too lazy, didn’t click the link copy/paste:

• .ml domains (the one fmhy.ml was on) has been reclaimed by the Mali government
• Freenom is also being sued by Meta (and has been for the past few months)
• Both of these have resulted in fmhy, along with a lot of other domains, to be unresolvable
• Changing domains will cause us to have to refederate and start mostly from scratch (although we might be able to transfer posts and users)
