Isn't a proxy is another SPF (Single point of failure) ?

That sounds like an interesting idea to use squid to load balance between the two servers. I need to do something similar in our lab and been trying to figure out the best way to do it.

I'm not familiar at all with squid itself so I may be completely off, but a load balancer does sound like an option.

So, how are others doing this? I have a server set up here in my primary data center. We're monitoring a few thousand hosts right now with a large number of custom externals.
I've been tasked with setting up a fail-over or disaster response server in case our primary data center has issues. All of our clients are currently configured to send their messages to the IP address of our primary server.
Now, I could just copy the bb-hosts file to the DR site, but then I would only get the network tests since the clients all report to the primary.
I run two completely separate systems in parallel, and have the clients report to both of them. The system at our disaster center has the paging module disabled (just disable the [bbpage] section in hobbitlaunch.cfg), to avoid double alerts - it is simple to activate it, if necessary.
I was thinking of using Sun Cluster(hb on Solaris) or HeartBeat(hb on Linux) but then how can I configure the Cluster solution to failover from one site(Florida) to another(NewYork) ?
I believe this setup is the most simple failover solution at the only expense of extra network bandwidth usgage to the secondary hb server.

Config files are rsync'ed from the primary site to the disaster site regularly.
