Their IP range is from 5.113.x.x to 5.126.x.x. None have hashed fingerprints. Is it okay to let these guys go? Can they harm or slow Tor? Should I ban them? I'd like to learn from this. This is probably a connection error caused by Iranian censorship. We're working on anti-censorship and stats fixes, but I can't find the tickets right now. In the meantime, try using a lower value for Tor's DoSConnectionMaxConcurrentCount option. The consensus value is 50, but you should set your value based on the number of connections from a single IP address. Or just try 25, then 12, ... If no single IP address is problematic by itself, you can use a firewall to limit the number of connections, or the new connection rate, from an entire address block.
