    Not to start a debate but I've used OpenDNS since last year and been
    VERY happy with it.... use it in situations where there is no localized
    DNS server available....

    And yes, to agree - open resolvers are very badly abused .. I'm
    surprised it took them this long...

    Testing from an l3 customer network which got responses and a non-l3
    customer network which did not implies that they finally clamped down
    on non-customer use of their anycasted resolvers.

    Open resolvers are seriously abused by botnets and related baddies.
    Perhaps you might need to run a set of resolvers, or get your service
    provider[s] to give you something similar to well-tuned anycasted
    resolvers.

    Cheers,
