Not really, it was expected to something like this will appear. Kelihos sinkholing also criticized by homemade security "experts". It is always pretty cool criticise others work when yourself you doing nothing and hiding this under the "private converstations" 600+ length words BS blogposts.

Don't think that this is new, I saw it at least 4 month ago. Why you decided that this is different version of ZBot?

"One of the botnets was up and running again within 24 hours of the takedown on a brand new c&c server and continued with its business as usual."

Is this true?
When you are running botnet and really thinking about it security you always have a plan B. Backup/alternative C&C servers, and maybe reserved bot version (Kelihos example). Only a complete takedown combined with law enforcement actions can guarantee that botnet is really dead at forever. So it is not a something unusual, or a fault from Microsoft. Authors of this article should do something instead of searching for mistakes in others actions.
