 just hoping someone will take real interest in looking into this. Which is
 why I am able to offer access to a server that is currently being
 attacked. I believe I saw a chat log of you first discussing complex mode
 in 2015 for OnionBalance. Do you have any links for how to enable
 it/configure it? I am going to try it out to see if it is a resolution for
 this, with the theory of introduction points being attacked.

 onionbalance, because it was harder to implement and we thought there was
 no real use for it.

 display the attack. I want debug or info logs that last for 1-2 hours of
 the attack and display the whole Tor lifetime (from startup to shutdown).
 Please sanitize them correctly (make sure that guard names and onion names
 are not visible).

 I will provide you with any logs I can later today. Could you please send
 a full list of anything that could help in debugging just to make sure you
 have everything relevant? Thank you
