Because this is only "poor man's load balancing". You maybe get (more or
less) equal load on rr'ed servers, but you can't fix your DNS servers (and
every other one caching your results) to not give out the A record of a
failed server.
It really comes donw to using LVS/keepalived or pen (I didn't even know it
exists before this discussion), or an expensive black-box solution (From F5,
Cisco, ....).
