Waves of (bad) addresses being gossiped

These are two plots from March 2023 I did back then. On the y-axis is peer_id (higher id/newer connections are further up). On the x-axis is time. Red indicates a “bad” address (I can’t connect to it) and green indicates a “good” address which I can connect to and do a version handshake.

Both of these show that:

  • all of our peers send us more addresses at (there’s less white space to see)
  • most of the addresses are “bad” (there’s more red dots to see)
  • during the spike, we get inbound connections at a higher rate and they are mostly short-lived and send us a few bad addresses (the red dots without any other addresses afterwards)

I’ve yet to check if the recent spikes still show the same behavior. I do have a fair bit of historical data on this though.
