Ah right, the routes need to be avail before considering the yoko service up.  Same for the PB server.  I do wonder if HTTP/PB requests could come in before service is marked up and thus cause errors.  E.g. creating a coverage plan requires that the yokozuna service be marked as up, but running a HTTP/PB request requires that a coverage plan be calculated.  So a chicken and egg scenario.  I wonder if @seancribbs knows of any startup races between PB and service?
