Visualizing DDOS

Visualizing a cyber attack on a VOIP server :: data viz having a "pretty" moment

So this is a win/fail video.
Frankly it's meant to be a data viz so it should tell me a story, and in a way it does, the actual narrative is quite clear - but there is no discernable meaning to the lay person. I have NO idea what is going on... even though something clearly is and that there are consequences to this terrible thing.
On the other hand it's terribly pretty. and the Pachelbel is (as noted) a nice change. Bemused.
