One must take care in the design of such Tor network scanning tools to not make successive circuits through the same relays repeatedly. Instead relay pairs should be shuffled. Yes AND if circuit building A->B fails but B->A succeeds then a subsequent A->B should also succeed. On Sun, Sep 17,

Hi, I am running a relay but 4 out of 8 directory authorities appear to being blocked by my ISP. There is no route to the blocked authorities and the last responding tcp traceroute hop is an ISP machine. There are routes via IPv6 though. Is there anything I can do to get my relay in the
