An exit relay that has just been updated to 0.2.4.17-rc produced this message
Sep 07 19:59:30.996 [Warning] Your Guard maisterikaarna ($C3B7CC79FD4E302AF8956A7B02F0FC7AAB4A6AF8) 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 52/151. Use counts are 0/0. 52 circuits completed, 0 were unusable, 0 collapsed, and 1 timed out. For reference, your timeout cutoff is 142 seconds.
Are there any recommendations?
