Info on DDOS attack on EasyDNS
An update on the DDOS attack that knocked out gersteinlab.org for a day http://blog.easydns.org/2013/06/04/post-mortem-of-the-june-3-4th-ddos/
Things to note: easydns is still vulnerable to this kind of attack. They are implementing design changes to mitigate future attacks.
