Twitter told to store Russian data in Russia

The Russian government has demanded that Twitter store the data of its Russian users on servers hosted in the country, a sudden change of tack that could vastly complicate the company’s relations with regulators in Moscow and lead to its being blocked in the market. The remarks by Alexander Zharov, head of Roskomnadzor, the internet regulator, come as thousands of Russian and foreign companies scramble to comply with new privacy rules.
