Placement of Witness in configuring VCSA HA

Aloha,

I am beginning the process of setting up VCSA HA. I have one VCSA serving three very well connected sites on island. I will call them
best, better and good based on their internal condition. VCSA is at best and the failover VCSA will be at better. I am at a loss as where
to put the witness. For each site, I can think of three reasons to put it there and three reasons not to put it there. The reasons have to
do with best practices and logic and not with the state of the sites themselves.

Any ideas are appreciated.

Bill
