 Today I was faced by an DDoS attack which looks different from all the
 ones I observed in former times.

 Former attacks shows a characteristic where the malicious IN traffic was
 just on top of the usual network load (as seen in
 https://www.zwiebeltoralf.de/torserver/graph.png).
 The attack today looks like that the IN traffic supersedes the usual
 network load completely
 (https://www.zwiebeltoralf.de/torserver/graph.svg).

 The system is a stable hardened Gentoo Linux with latest kernel.
