Russia's parliament has passed a bill that could see Western technology firms barred from operating if they fail to store Russian data within the country.

The legislation would require Silicon Valley companies, such as Facebook, Google’s Gmail, and Microsoft-owned Skype, to relocate Russian customer data back onto Russian soil in order to allow authorities to legally acquire and inspect data at will. Currently, Russian authorities have no powers to acquire data outside its borders, unless they submit a lawful mutual legal assistance request, which can be denied by that nation.
