Because the ingress controller works using the [synchronization loop pattern](https://coreos.com/kubernetes/docs/latest/replication-controller.html#the-reconciliation-loop-in-detail), it is applying the configuration for all matching objects. In case some Ingress objects have a broken configuration, for example a syntax error in the `nginx.ingress.kubernetes.io/configuration-snippet` annotation, the generated configuration becomes invalid, does not reload and hence no more ingresses will be taken into account.
