No-IP's Formal Statement on Microsoft Takedown 
This smells like BS, this also isn't the first time that other entities have had to step in to cleanup their crap.Especially this quote:
"Apparently, the Microsoft infrastructure is not able to handle the billions of queries from our customers."Azure DNS, Microsoft.com, Bing. Yeah, all of those already require billions of DNS queries.
I don't doubt things are not working correctly, but insinuating Microsoft can't handle the load just makes their case smell even worse.
