That's what it was!

I added 2 other relays that I recognized from the recommended list, and my list exploded from 7 to 35!

Thanks, I wasn't registering how that worked. I had assumed that my relay list was kept specifically in the client I was using. (ie. on Iris if I entered it, then as long as I logged back in on Iris, I would be delivered the relay list)

That's really interesting. I wonder how I can broadcast the list better to be sure that most of my relays have my whole list 🤔
