Hi David, Thanks for getting back to me so quickly.
I had seen the secondarySorryServer config when first looking into this. I really want load balanced 'Sorry' service, instead of fail to first 'Sorry' service and if that's also down, fail to secondary 'Sorry' service. Thanks for the idea though :) Richard.

Not true load balancing but at least more than one 'Sorry' server in the loop. Cheers, David.
