Hello Tor users, Help me with a problem please. I have a small exit/backup & directory VPS in Finland [1]. This last week the server (and Tor) have been overwhelmed with non-Tor IP addresses. This may be a small version of a DoS attack. I took the server down for a few days but when I restarted it the attack was there before Tor users. Eventually, the load caused kernal crash. I noticed this last week, that my Consensus Weight had dropped from 5500 to 68. Does anyone have an efficient way to defeat this ongoing attack? --potlatch
