Emailing "Another ISP Cuts Off the Srbizi Botnet"
The Srbizi botnet is the one that went offline a few weeks ago when McColo went down (see [McColo and the Difficulty of Fighting Spam](http://www.internetnews.com/commentary/article.php/3786406/McColo+and+the+Difficulty+of+Fighting+Spam.htm)).
Apparently, it recently moved to Estonia but has just been cut off (an impeccable source points me to [this article](http://www.computerworld.com/action/article.do?command=viewArticleBasic&articleId=9121758)).
Experts say that future botnets will not rely on single servers so much (one term for these future pests is "[headless botnets](http://www.google.com/search?hl=en&q=%22headless+botnets%22&btnG=Google+Search&aq=f&oq=)").
Nevertheless, bravo to the ISP community for stopping this one . . . for now.
