You could use Traffic Control to do that ;)

Another option is to place several Traffic Server boxes behind a VIP, i.e. a router or load
balancer that owns a common IP and distributes connections to whichever Traffic Server box
is alive.  A router capable of basic ECMP routing can mostly do this.  Or a dedicated state-aware
load balancer can detect that a Traffic Server box has gone done and send new connections
to other servers.

I believe what he's saying is that this behaviour is up to the client. The client will try
to connect to one traffic server, and if it fails then the client just needs to know the URL/IP
of the secondary server and try that - without any direction from Traffic Server.
It makes sense, because in a failure scenario you can't rely on the Traffic Server to be working
properly, so the safest thing to do is handle it yourself if possible.

We have this configured on the client side, e.g if the client connection to trafficserver001
fails the client will attempt a connection to trafficserver002.
