Interesting to see. I have similar stats. 10 connections from 188.214.30.0/24, second up 8 connections from 178.16.208.0/24. Thanks!

connlimit per /24. it does more good than evil.
Any guidance on the specifics? Like how many concurrent connections to allow per /24? Not sure what's expected from legitimate user traffic through the relay... don't want to make things worse. _______________________________________________ tor-relays mailing list tor-relays@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays

Actually this also caught my attention on this 10 nodes from 188.214.30/24:
https://atlas.torproject.org/#search/188.214.30
All from Romania, relays, ports 443/9030, good bandwidth 17-26MiB, uptime almost identical, and no family member set. One is even named CIA :)
Contact is set to none also.
welcome!

my second and third positions are similar:
9 217.12.223.0/24 (family and contact info set) 8 178.16.208.0/24 (family and contact info set, too)
