A BRICS Internet, the Euro Cloud, the Iranian Internet. Governments across the world eager to increase control over the World Wide Web are tearing it apart. Iran seeks to develop an Internet free of Western influences or domestic dissent. The Australian government places restrictions on health data leaving the country. South Korea requires mapping data to be stored domestically. Vietnam insists on a local copy of all Vietnamese data. The nations of the world are erecting Schengen zones for data, undermining the possibility of global services. The last century’s non-tariff barriers to goods have reappeared as firewalls blocking international data flows.

Data localization requirements threaten the major new advances in information technology — not only cloud computing, but also the promise of big data and the Internet of Things. Equally important, data localization requirements undermine social, economic and civil rights by eroding the ability of consumers and businesses to benefit from access to both knowledge and international markets and by giving governments greater control over local information. Legitimate global anxieties over surveillance and security are justifying governmental measures that break apart the World Wide Web, without enhancing either privacy or security.
