Sep 18 09:57:09.846 [Warning] Your Guard safdef 
($09C0E63BD41FE86A31CB3FB27C4D54F7D49A1F7C) is failing a very large 
amount of circuits. Most likely this means the Tor network is 
overloaded, but it could also mean an attack against you or potentially 
the guard itself. Success counts are 76/170. Use counts are 11/11. 78 
circuits completed, 0 were unusable, 2 collapsed, and 2 timed out. For 
reference, your timeout cutoff is 361 seconds.
