my relays are still available on web clients i use cause i think they all use nip-65. i use https://metadata.nostr.com/ to back up my relay list, but i don't think it broadcasts relay list updates as a kind 3 event. i should try it though.

Your relays are still on the web clients but not on Damus. Interesting
Only client that ever rugged my relays was plebstr. Do you use it ?
i think most of the web clients have switched to using nip-65. i haven't used plebstr in a while. i think coracle or primal rugged my kind 3 relay list this time.
