Attacks to root DNS-servers

Over the last few days, we have seen some DDOS-style attacks to some root DNS. Still a lot of speculations are going on. If you look at the traffic pictures at: https://dnsmon.ripe.net/dns-servmon/domain/plot?domain=root&day=5&month=2&year=2007&hour=16&period=48h&plot%2F=SHOW you see that g and h and partly l got most of the traffic.

US-CERT issued bulletin (https://www.uscert.gov/current/current_activity.html#dnsanom) and it started to make the press https://hosted.ap.org/dynamic/stories/I/INTERNET_ATTACKS?SITE=WIRE&SECTION=HOME&TEMPLATE=DEFAULT but at the moment nobody seems to have a clue what is going on and especially why it is going on...
