[c-nsp] GSS and ACE

[Nick Griffin]

So say I had 2 datacenter locations geographically disperse and I'm not
running BGP. I have similar web and smtp servers at each locations. I'm not
so much concerned that traffic gets load balanced to a cluster of servers
when traffic enters a particular data center (which is an ACE application),
instead I'm concerned about D/R. Say I lose DataCenter 1, I want some DNS
magic to take place to say that mail.mydomain.com has moved from 10.1.1.5 to
10.1.2.5 at Data Center 2. Does that make sense?
