We just switched to a new database system (postgres instead for elasticsearch) to get better database speed.
It’s looking like some small fraction of the data didn’t get copied over. We still have the old data and are in the process of copying it now, so if something is missing, it should be back within the next couple hours. Really sorry about this.
As a side-effect of the recovery process, anything deleted while this is going on (starting from approximately ~2 hours ago) will get restored, so if you see something that should be deleted pop back up, just delete it agin.
