Why is the Circle suspended, but not the Hammersmith & City? Don't

Well, as a guess, I'd say that as there is no service
between Liverpool Street and Barking, Hammersmith & City
Line trains will fill out the schedule to Hammersmith so
there will be no need and no requirement for Circle Line
trains to provide the same service.
