YAY!!

The answer I hoped for!

So does that mean, perlbal is running on both machines?

Requests always go to say Machine A (IP 1), perlbal decides where the
request should be completed, Machine A (IP 1) or Machine B (IP 2), is that
right?

If Machine A fails, wackamole moves IP 1 to IP machine B, so that all future
requests are served by Machine B.

Please correct me if I am missing something here

Thanks a lot!! :)
