Well, that might depend on your TTL's
and the speed of the repair boyz in the NOC...

Keep in mind that the world will consider your DNS
"broken" if you do this.  DNS reporting services
will flag you if your 2 servers on are the same 
*subnet*, much less the same IP addy...

Obviously, what people think is of little concern
in your situation, I'm guessing....
