Please note that Puneet was asking for other operators' experiences, not the opinions of those of us who believe we should tell Google what to do. (And, yes, I certainly put myself in the latter category.) I, too, would like to hear if other resolver operators see this, and if possible to what extent they are seeing it, and if we're really lucky to hear at least a few names for which this is happening. The latter is not to name-and-shame, but instead to be able to talk to the authoritative operators about what their configuration is so that we can maybe guide others away from this path.
