Hi everyone,

I have a question regarding my Tor relay’s lifecycle.

Since the beginning, I have noticed that the guard and middle probabilities fluctuate significantly. I have not observed this behavior when comparing with other operators’ relays. After some time, the relay receives the Guard flag and the middle probability decreases, later it loses the Guard flag and the middle probability increases again. I waited for a long time to see whether this would stabilize, but the behavior has remained unchanged.

I would like to ask what the possible reasons for this could be, and whether it might be related to my configuration.

Thank you in advance.

P.S. If you check the relay statistics, please ignore the low consensus weight and probabilities during the last month, that was caused by my own mistake.
