Yeah, after what happened to VLemmy I decided to start my own instance, that way as long as I maintain it I know for a fact that it won't just go down.
Pretty much, just vanished off the face of the earth. Donation links got shut down too. I've seen some discussions alleging there was an incident with law enforcement (A user uploaded "japanese underage child" content to the server, which was illegal in vlemmy's juristiction - ireland IIRC?) and shortly after that the server disappeared
Basically. There was no announcement and no one's really sure what happened, the server kinda just died one day and the admin never said anything about it.
Would be nice to have some form of account portability that would work after a server vanishes. Like, way to register a pubkey on a server and then register a signed message at another server that this is your new account.
That would be very nice, though how it would be implemented would be difficult. One way it could potentially be done is the new server has to request control from the old one, that would be fairly secure but would introduce the problem of "What if the old one no longer exists?" It could be that there's a key that you send with your activity to verify it's you which can be moved to a new instance, but then you run into the issue of how to stop a malicious instance admin from getting your info. You could have a centralized authentication service, though many dislike that because it goes against federation to some extent. I know on Mastadon you can transition your followers, I don't know how it works but it's possible they figured out a good solution.
Was a budding smaller instance and then suddenly without warning it disappeared. I'm not sure if we know what happened, but it's actually one of the reasons why I want to stay on the bigger instances. Smaller ones have the risk of just poofing away one day...whereas larger ones may have occasional downtime and issues, your account is less likely to be unexpectedly lost to the void.
