Un rappresentante USPS ha chiarito la situazione. In pratica Poste Italiane non vogliono pagare USPS per il servizio di tracking fornito ai clienti delle poste e per questo hanno smesso di fornire i dati: "Yes and you are correct essentially. From my personal knowledge Italy had not been paying for the service even though we were providing it's customers with the information. So since they were in breach of the agreement, USPS stop providing the service. That's from my understanding."
