Sometime early this morning, our database started having issues, most likely due to a disk corruption issue.
Unfortunately the postgres database was unrecoverable, and we had to restore from a nightly backup, so a few hours of posts and comments will be missing.
Apologies again for the downtime, and for the disruption.
It strikes me that there is the potential to use trusted remote servers as a means of recovering the lost data. I mean, nearly every lemmy instance except lemmy.ml will have copies of the missing data, and given the hugely redundant availability of that data (including the ability to compare from multiple sources to establish/verify trust), using that data to rebuild missing content seems like it could be useful functionality.
If I understand, federating contents through ActivityPub only works once. Sounds a good feature to re-download contents again, but may introduce additional work as there should be some way to know if a content is missing then another job to rebuild
