To jump right into this thread without reading back through it...
Other alternatives is using DNS for load sharing (won't help much with
failing nodes though), using a load balancer or use some kind of anycast
setup (heavily used for example by the DNS root servers).
The last one is where you use routing to get traffic destined for a
certain IP address to end up at different destination hosts based on for
example the region the traffic is sourced from, but discussing that
would be quite off topic for this mailing list - use google to search
for example "dns anycast" to learn more.
