Yes, AuthBy HASHBALANCE chooseHost() behaviour was enhanced in Radiator 
4.25.

What it now does better is that when next hop Hosts go missing, the 
requests are distributed more evenly while not changing the next hop if 
the default target for a request is still alive.

It already knew to stop when MaxTargetHosts configuration parameter was 
hit or if there were no Hosts left that had not been tried yet. 
MaxTargetHosts was moved in 4.14 from VOLUMEBALANCE to AuthBy RADIUS and 
therefore is available for all its derivatives.

I'd say immediate help with recent versions is to use MaxTargetHosts. 
What we'll do is to revisit the logic, as suggested by Frank, for 
LOADBALANCE and for other proxy algorithms too, as needed.

Frank, thanks for taking a look at this!
