It depends on:

* wether you pick the first address (which does not work) or the
second (which does work). Pure luck. "dig A broken.bortzmeyer.fr".

* how your network infrastructure reports that the first address is
not reachable (immediate ICMP "Network unreachable" or black
hole?). 

* how your browser reacts to this unreachability.

The purpose of this little experiment is to see wether a pure DNS
redundancy solution is realistic for HTTP (I do not think so).
