As per our post:
http://blog.easydns.org/2013/06/27/dnsresolvers-open-resolvers-will-be-shut-down/
The DNSResolvers.com free and open public resolvers will be shut down, imminently (like tonight, if we get DDoS-ed against them again).
We'll keep them up for awhile if we can so everybody can migrate off, but if you or somebody you care about is using them, please make other arrangements as fast as possible.
thankyouverymuch
