Could you clarify, here, Jared?

Do "open DNS customer-resolver/recursive servers" *per se* cause a problem?

Or is it merely "customer zone servers which are misconfigured to recurse",
as has always been problematic?

That is: is this just a reminder we never closed the old hole, or 
notification of some new and much nastier hole?
