The Chinese government is cracking down on a key technology that Web surfers use to protect their privacy and get around online censorship, according to Bloomberg News.
Some of the country's biggest telecom companies - the state-run China Mobile, China Unicom and China Telecom, Bloomberg said - are being instructed to block customers from using virtual private networks, a technology that redirects a person's Internet traffic through other servers to make it look like they are connected to the Web from someplace else.
For years, Chinese citizens have used VPNs to circumvent the country's Great Firewall, the colloquial term for a series of blocks and restrictions imposed on the Internet by Beijing in an effort to ensure that only a filtered version of the Web is visible to most of the country.
VPNs have allowed tech-savvy Chinese Internet users to access restricted news sites and social media platforms such as Twitter and Facebook.
China has periodically clamped down on Internet users' attempts to evade the Great Firewall. The last such campaign took place in 2016, prompting widespread reports of VPN outages. But the government has intensified its attack on VPNs in recent months.
