"Kuailian VPN," boasting 20 million users, announces its withdrawal from China! Mainland China imposes the strictest internet censorship in history: data centers directly disconnect, and circumventing the firewall becomes a crime of subversion of state power.

For Chinese netizens who rely on overseas information for their livelihood, the last line of defense seems to be collapsing.

On April 28, LetsVPN, a well-known VPN service in China with over 20 million users, released a heartbreaking announcement: officially announcing the termination of its business operations in mainland China , closing its payment channels in mainland China, and initiating a refund mechanism for users who paid after April 8.

After a grueling 20-day battle, Kuai Lian admitted defeat, saying he felt "willing but unable."

In the past, QuickConnect VPN's strongest selling point was its brand slogan, "Always connected." However, in the face of this sudden wave of internet censorship, that reputation was ultimately shattered.

In its official announcement, Kuailian described the move as a "difficult decision." They revealed with resignation that since the escalating internet censorship in mainland China in mid-April, widespread service disruptions had occurred. The technical team had been attempting adjustments and repairs almost "every hour" for the past 20 days, but ultimately confirmed that they were unable to effectively resolve the issue, admitting that they were "powerless" in the face of the current national-level technical blockade.

Unplugging the network cable + AI recognition: the strictest lockdown operation in history

The collapse of Kuailian is not an isolated case, but rather the tip of the iceberg of China's recent "nationwide internet censorship campaign." According to intelligence gathered from multiple sources, this campaign, led by the Cyberspace Administration of China and the Ministry of Industry and Information Technology, and involving the three major telecom operators, began in March 2026. Its intensity and technical sophistication far surpass previous efforts in this area.

• Infrastructure is being directly "dumped": Authorities are requiring data centers and IDC service providers to conduct self-inspections and block all cross-border traffic (including traffic from Hong Kong, Macau, and Taiwan). Any abnormal IPs detected will result in physical port disconnection or even system shutdown. The gray area of ​​"renting official server rooms for relaying," previously exploited by circumvention service providers, has been completely eradicated.
• The AI ​​system "Tiangou" precisely targets threats: In the past, firewalls relied on protocol signature recognition, but now each province has independently deployed monitoring systems (such as "Tiangou") that incorporate AI and behavioral recognition technologies. This renders traditional obfuscation techniques completely ineffective.
• Legal and political characterization escalates: According to sources, the top leadership has designated VPNs as "tools for subverting state power," aiming to prevent cognitive infiltration. The revised Cybersecurity Law (effective in 2026) provides stricter penalties, significantly increasing the risk of fines and summons for questioning for individuals using VPNs.

With the digital iron curtain falling, where will cross-border industries go from here?

The impact of this swift and decisive action has extended far beyond political dissidents, severely damaging China's massive cross-border e-commerce, foreign trade, academic research, and AI developers and Web3 professionals who are heavily reliant on GitHub and overseas exchanges.

Currently, the industry consensus is that "100% stable circumvention tools" no longer exist. For companies with legitimate cross-border needs, authorities are forcing them to apply for official registration channels that are under full surveillance; while individual users, besides quickly requesting refunds from defunct tools like QuickConnect, are forced to switch to the more costly and risky eSIM international data cards or try multiple mainstream international VPNs to diversify their risk. As this digital iron curtain grows ever thicker, the decoupling of China from the global information network is entering a suffocating new phase.
