That's a start, thanks. I can't see any property that's about the "size", whatever that means.
That's in the nostr.band statistic I posted elsewhere in the thread. Smaller relays aren't listed.

I see... nostr.band is not actionable... just a picture. At least nostr.watch has an API, but there's no users/events count apparently. I don't see those resources to be really useful unfortunately. Any knowledge of some actual source of data?
probably this https://stats.nostr.band/
