Recommend adding wss://hist.nostr.land to your relay list. If this happens again in the future you'll be able to recover on nostr.land.
I also do monthly nostr maintenance using
@Plebs vs. Zombies ๐งโโ๏ธ๐ช which also creates a backup before wiping nostr Z's and for desktop I recommend using
@Sidecar ๐ธ as a signer. Or a signer on steroids. You can bootstrap your relays and do backups.
Oh, and maybe check out mutable.top
