<div>For what little it's worth, I've seen this somewhat even on 9.8 (it's not new), though increasingly on 9.9...not saying it's BIND specific, just that I've hit these kind of annoyances with remote servers awhile now.</div>
<div><br>
</div>
<div>I've tried explaining this on numerous internal email threads, tickets, webex (calls are great), etc...but it is quite frustrating, because so long as reasonably savvy users can "dig @8.8.8.8" and get a response, they don't believe your server isn't broken.</div>
