The State Duma, the lower house of parliament in Russia, approved a bill Tuesday aimed at tightening government control of the internet in the country.

The bill, which sponsors said is aimed at securing “reliable” access to the World Wide Web independently from the control of other countries, would force Internet Service Providers to route all internet traffic through connection equipment physically located in Russia as well as establish a secondary Domain Name System independent from the international standard for the country.

The bill now passes to the higher chamber of parliament, the Federation Council, for approval, followed by a signature from President Vladimir Putin to make the bill law. Opponents have decried the measure as a step closer to government control of the internet, warning of censorship and privacy concerns should the bill pass.
