Afaict, the circuit server runs on every host, and is aware of the other nodes, coordinating with peers without a single master. So if one host fails, the other circuits can still function, broadcasting their underlying services. "Clients dial into [any] circuit server in order to interact with the entire system. All [circuit] servers are equal citizens in every respect and, in particular, any one can be used as a choice for dial-in." However, the example diagrams I've seen, include services which aren't masterless or even multi-master, so the app/system the circuit cluster supports will surely fail in some way.
