Vietnamese fear Facebook blockage

Vietnam's more than 1 million Facebook users are worried that their government may be blocking the social network site, the San Jose Mercury News reports. "Over the past week, access to Facebook has been intermittent in the country, whose government tightly controls the flow of information. The severity of the problem appears to depend on which Internet service provider a customer uses." One ISP's technician said his company had been ordered by government officials to block Facebook, but senior management said that hadn't happened. "Access to other popular Web sites appears to be uninterrupted in Vietnam, a nation of 86 million with 22 million Internet users."
