[tor-relays] Logfile: Tor overloaded or attacked

Hi,

the relay is managed by me and I checked the logs.

There is no evidence of any attack against the relay itself, the only
thing i could see was packet loss on connections via Frankfurt. So I
assume the hoster seemed to have some network issues which are clearly
resolved by now.

Regards,

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 105/214. Use counts are 71/74. 194 circuits completed, 9 were unusable, 80 collapsed, and 9 timed out. For reference, your timeout cutoff is 60 seconds.
