The first 2 comments made on the now dead FMHY instance shall remain remembered
Unfortunately what seems to be the cached version of lemmy.fmhy.ml is now slowly disappearing from Cloudflare. Those 2 comments have now been lost as well along with most of the content.
From what I can gather losing the domain means losing the instance. Obviously that sucks but if I was designing Lemmy I wouldn't think of "what if the Malian government suddenly decides not?".
The reason they haven't yet come back to another instance is they're trying to work out how to migrate and keep the instance while not breaking anything.
This is more like activitypub problem. You can't really change domain in activitypub. Even in mastodon, you can only add another alias domain. Losing your original domain is catastrophic. I'm actually interested whether the activitypub devs are finally going to address this. I'm also interested to see what kind of hack FMHY use in order to save their instance.
Not a (permanent) solution, just a very (very, very,...) stupid idea, that I am not even sure would work.
What happened? They don't own the domains anymore, the DNS records were removed so those domains don't resolve to anything. But maybe they could be locally resolved by each instance. I added these entries to my /etc/hosts file when the DNS records were deleted:
This allowed me access to FMHY (while it was still up).
Even if this worked, why would it be stupid? Well it would have to be manually set by each instance. And those IP addresses may change from time to time, so it would have to be manually updated again, by every instance.
This doesn't solve the main problem thought, in which the instance can no longer federate with other instance via activitypub. You can't expect other instances to manually override their DNS in order to federate with fmhy again. Also, https will break as soon as their current certificate expires, at which point no instances can federate with fmhy even with dns override.
Hopefully this issue will force activitypub developers to rethink their approach with domain handling.
You can think of it like group chats. Each and every chat is an instance. And to be federated just means that two chats have agreed, that there is one person who copies the text from one chat to the other.
In principle this, but much more organized with communities (sub groups) and subscriptions and the like.
Now in reality this is much more complicated, because people want to be identifiable across instances, which is why you can't have just one person in the chat posting Just the text, they need to mention who it was that texted that.
Losing the domain was like the person who was in both chats disappearing and you can't register with their name, but someone else doing what they did, would mean that everyone would need to update their filters, because "I said the first time, that I don't care about your weekend, Carl!"
Some bridged chats in telegram might be better example. They use bots to bridge messages between discord, matrix, telegram etc.(eg. t.me/STKInternational (supertuxkart game community lol))
