Technically I could. But as with mastodon.world I have made a promise to ensure continuity by creating a team of sysadmins and moderators with access, and making sure it can be transferred to them might I get hit by a bus, or get bored of this.
But I hope there will be a feature to export your posts soon so you can create your own backups too.
I mean that’s every web site all the time though. The owner/admin can always just delete it.
Short answer – nothing.
Longer answer – Those communities, posts and comments will still exist on the other servers, but sadly interacting with them will not federate that data to other instances anymore, since the host instance is no longer active.
So you would still be able to see the posts and their comments on other servers?
Yep, but if you reply to said post, only other users on YOUR instance will see those comments. Any other instance and it would be like you didn’t reply at all.
OK thanks. I am still a bit confused at how it works tho, if they did nuke the website, where would the data from the post and comments be stored
So trying to not go into the technical details too much but when two instances federate with each other, they literally share all of the community, post and comment data with all other federated servers. But it’s the job of the host do manage that passing of data.
Now once the host decides to go offline, that activity of informing all other instances of “hey here’s something new about XYZ community!” no longer happens, but each instance still has the historical data from prior to them going offline. So you can still see that old data and still technically reply to it. Just that the host won’t tell other instances that you did reply.
So lets say lemmy.world and then lets take beehaw.org (I know they are defederated lets assume they are not) for example. All the posts and comments which are hosted by lemmy.world on hard drives or servers, are also hosted by beehaw.org and vice versa? So the amount of data is actually doubled in size?
Yep. Add in a 3rd instance and now you have 3 copies of the database, essentially. It’s just that each instance is responsible about telling the fediverse when updates occur to communities on their instance.
If the fediverse gets really big, lets say the size of reddit, it may be hard for all the different instances to store all that data on their servers
