Well, the above would work if proxy D is to be accessed by all clients. But in our scenario, proxy D is physically and "topologically" far away from other clients. Proxies A, B, and C serve different physical sites/networks, but are siblings with one another as they are relatively close.
The objective is to make A, B, and C have a "failover" connection, so as to continually serve its network.
