My hosting provider alerted me of a DDoS attack on one of
my relays. It started around 2016-01-26 12:42 UTC. They claim
they tried "filtering, routing, and network configuration
changes" to mitigate the attack, but as a last resort they
temporarily disconnected the host from the network for 3
hours.
I know such attacks are not uncommon, but I'm curious if
any other operators experienced a DDoS around the same time?
I'm also curious to know more about the nature of such
attacks -- what type of attack was it, what is the general end
goal of attacking a random Tor (non-exit) relay, etc. My
hosting provider is unable or unwilling to share additional
information.
