Hi, I`ve read your post and questions, also about your 2 Raspberry PIs with the same setting but different locations. I thought about it and my question is: Did these to PIs got a new fresh identity on day zero? If not, it`s worth a try, probably. Kill the old identities and let them by. My fundamental idea is (and that`s why I am writing this): Does my behaviour with the relay (restarting, upgrading, not be onlinening) effect the measurement and therefore the throughput of my relay? Cheers, Patrice
