A screen shot of the popular WhatsApp smartphone application is seen after a court in Brazil ordered cellular service providers nationwide to block the application for two days in Rio de Janeiro, Brazil, on December 17, 2015. The unprecedented 48-hour blockage was to implement a Sao Paulo state court order and was to take effect at 0200 GMT Thursday, although it was not immediately clear if service providers would acquiesce to the order.The court said WhatsApp had been asked several times to cooperate in a criminal investigation, but had repeatedly failed to comply.
