this happens on Snort too. i think this is a result of relays getting hammered and not responding in a timely manner.

Relay delay 😉
Same on Iris and likely relays. Could this be from the limitation of up to 3rd degree separation? Also under nip65, if event is not pushed out to the list, you write to the few you select and read from what you are tagged (out of your follower list), but not sure how the relays r/w is defined . But can definitely feel the diff in limitation of accessibility
