As you reading are undoubtedly aware now, the Lemmy.one instance experienced a massive failure this weekend. Unfortunately the data was not in a recoverable state, so the server was restored from a July 26th backup, and data after that time is likely lost.
Since this occurred while I was out of town, I haven’t had the time to collect all the details of what happened, so I will have to post more information at a later time.
I don’t underhand why the comments disappeared from a different server.
Maybe because that server synced with this server, assuming this is your home instance. If the comments aren’t on any record here, they might get deleted from the other server.
Option 2: you attempted to make those comments but they never went through because this server was already having problems. So they never truly existed on the other server?
I’m just guessing, I don’t know how the hell this fediverse stuff works.
