-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hello. One of my relays, 54C85B97B4A5253483AA269B341C4CCF9328C443, had 400 Mbps up and only 50 Mbps down for several hours. Performance got so bad that could barely SSH in. Unfortunately, I rebooted before doing diagnostics and the problem has not happened since, so I couldn't see if Tor logged asymmetric bandwidth use in its heartbeat. Nothing in the logs indicate anything abnormal. This started on Jun 25th, 12:30 AM UTC and continued until I rebooted at around 4:00 AM UTC. Tor's CPU use was 100% for the duration of this event and the uplink was not saturated. Is this something that has happened before? Could it be some DoS attack? As far as I know, the only way to get Tor to use asymmetric bandwidth is to use it as a directory mirror.
