[AusNOG] DDOS mitigation

Fri May 10 19:16:08 EST 2013

No worries Nathan,

We can only comment on what we our global client base experiencing. All we
can say is that attacks are getting bigger, as confirmed by Gartner here:

http://blogs.gartner.com/avivah-litan/2013/03/14/are-the-ongoing-ddos-attacks-against-u-s-banks-just-the-calm-before-the-storm/

Our research team, called PLXsert, detail attack trends against our client
base every 3 months in our quarterly attack report which can be found on
our website link below.

Hope this is of value and you are welcome to forward any questions.
