Unfortunly you are not right here: The fix is available only on request by a
certified partner, not via the usual updates services. The fix is explicitly
marked to not be used in production enviroments.

And you have to know, that a parsing problem might exist, because your
application only receive "SERVFAIL". After you traced this "response" down
to a local software glitch, you might find the approbriate knowlegde base
article which urges you to ask a partner for the fix.

I wonder if this fix is installed in any other system than ours in the next
200km.

And those are ignored, because they come bundled with a DNAME record, which
stops the processing of the packet.
