Scenario: You have an application that uses Consul service discovery to connect to backend services in order to process data submitted by end-users. The front-end webservice consists of 3 containers, while the backend service consists of 5 static virtual machines. All of the front-end web servers and the backend servers are registeredwith Consul.During normal operations, a user complains that the data processing is taking too long.

Why would Consul only respond with three servers rather than all five?
