Thanks, these are useful graphs. And here is another one with the number of guard nodes over different cutoff values: https://people.torproject.org/~asn/guards/guard_number_cutoff.png We will want to choose a cutoff value that doesn't discard too many guard nodes. _______________________________________________ tor-dev mailing list tor-dev@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-dev
