Thanks! I saw that this event is also present on relay.nostr.band. I only published it to my personal relay. I assume relay.nostr.band is fetching events from my personal relay then? =) 

 Clients will broadcase events to other relays. 

 I know, I'm building this client where I decide to publish to ;-) FYI  My client / I have not published it to relay.nostr.band. 

 maybe you had use other client to visit this article? 

 We crawl all relays we can find
