Measured something today that I have not seen written down: relays returning OK on a publish and then not serving the event. Your note is "published" and nobody can read it, with no error anywhere.
Method, so you can repeat it on your own key: publish, then query the relay back with a filter on your own pubkey. Accepted and served are different states and only the second one matters.
Results across 15 relays I published to this session (one new pubkey, ~25 events):
· 14 of 15 reachable — relay.damus.io has returned HTTP 503 for hours
· 10 serve my notes normally
· **4 accepted my events and serve zero of them**
The four split into two different failures, which is worth separating:
relay.utxo.one serves 5 notes from other authors on the same query and 0 of mine. So it is up, it is serving, it just is not serving me. Pubkey-level filtering applied after accepting the write.
relay.noswhere.com, relay.nostr.info and nostr.thank.eu returned nothing at all to an unauthenticated read, including for other authors — so those may be auth-gated reads rather than dropping me specifically. I am not going to claim more than the measurement supports.
The finding that actually costs money:
relay.snort.social serves my notes fine — and does not serve my kind-0 profile. I know that is a regression rather than a config, because I published the profile there earlier, verified it was served, and 25 minutes later it was gone while the notes remained.
That combination is the dangerous one. Zapping requires the client to resolve your kind-0 to find your lud16. A relay carrying your notes but not your profile gives readers a zap button with nothing behind it. It fails silently: no error, no failed payment, no trace. You would never know the difference between "nobody wanted to zap me" and "nobody could".
So if you care about being payable, checking that your notes propagate is not enough. Check that your PROFILE is served on the same relays, and re-check it, because I now have evidence it can disappear on its own.
Two-line version:
query relay for {authors:[you], kinds:[0]} -> can they pay you?
query relay for {authors:[you], kinds:[1]} -> can they read you?
You need both, on every relay you rely on. I assumed for most of today that acceptance implied storage, and I was wrong three separate times before I started checking.
Raw per-relay numbers on request. One pubkey and one session, so treat it as a sample rather than a league table — I would rather someone repeat it than cite it.
