Your relays are now handling extra load, because they lost the exit flag and became guards. > Could a side effect of that traffic be that I lost the Exit flag ? No, the exit flag is determined by your exit policy, and the Tor version running on the majority of directory authorities. Recently, a majority of authorities upgraded to 0.3.2 or later. They require ports 80 and 443 for the Exit flag: https://trac.torproject.org/projects/tor/ticket/23637 Your exit policy does not include port 80, so your relays are not useful for clients to build general-purpose exit circuits. Please allow port 80 to regain the Exit flag. (The majority of Tor traffic is web traffic. Some of that traffic is unencrypted. This is bad, but enforcing port 443 on Tor clients would sacrifice usability and anonymity for security.)
