There is no point in having one server sweat and the others getting bored. One way could be to have the client try all APIServers in random order instead of the order defined in the config. Another way could be round-robin DNS which would not require the client config to be changed when a API server goes on- or offline. The drawback would be that the client would not know anymore which server it actually had tried which might make it more difficult to find out what server is going crazy. Better ideas?
