OK then. What nameserver daemon behaves like this?
various versions of IE cache either for 30 minutes or an hour irrespective of the times they get back from the resolver. see http://support.microsoft.com/default.aspx?kbid=263558 I believe gecko based browsers are guilty of this too (although to a lesser extent -- 10 minutes iirc).
Interesting that the article in question cites IE up to version 6. Did they change this behavior in IE7? I had a quick look, but my Microsoft-search-foo isnt great these days...
