An update:
- fmhy.ml is gone, due to the ongoing fiasco with mali government taking all their .ml domains back
- As such, lemmy.fmhy.ml is also gone, we are currently exploring ways to refederate (or somehow restart federation entirely) without breaking anything substantial
- We have backups, so don’t worry about data loss (you can view them on other instances anyway)
Currently, we have fmhy.net and are exploring options to somehow migrate, thank you for your patience.
Nope. Domains don’t store data. They can change domain and keep all the data.
Unfortunately, no.
Currently, activitypub identity is tied to domain name. While mastodon support migration as long as the old domain is still up during the migration process, AFAIK Lemmy doesn’t even have a process to migrate an instance to a new domain yet.
So basically, if you switch your instance domain, you’ll mess up all your federation network, unless Lemmy devs implement a solution soon.
