China targets Astrill and other anti-censorship VPNs ahead of celebration marking the 70th anniversary of end of WWII
South China Morning Post :
Context & Ripple Effects
The crackdown on commercial VPN services began earlier this year, when Beijing first blocked providers like Astrill and then formally acknowledged the campaign as an effort to foster the 'healthy development' of China's internet. The timing now — ahead of the 70th anniversary celebrations marking the end of WWII — fits a familiar playbook: tightening the Great Firewall around politically sensitive dates when authorities want to control information flows.
What makes this round notable is who gets caught in it: Astrill and similar services are the standard tooling for foreign businesses, journalists, and travelers in China, not just domestic dissidents. Each anniversary-level sweep raises the operating cost of staying connected across the firewall for exactly the audience Beijing can least afford to alienate.
First-order effects
- Astrill and other targeted providers see connections from inside China drop or fail outright during the celebration window, leaving their paying customers — expatriates, multinationals, travelers — without reliable access to blocked sites right now.
- Users in China must scramble to find working alternatives mid-crackdown, testing whichever provider has not yet been identified by censors.
Second-order effects
- Commercial VPN providers are pushed toward stealthier techniques to survive detection, a shift already visible as Chinese coders migrate to the open-source proxy tool Shadowsocks, which is harder to fingerprint than branded VPN protocols.
- Providers face reputational damage on reliability precisely when corporate customers evaluate renewals, pressuring the market toward either government-approved domestic services or technical cat-and-mouse.
Third-order effects
- Event-driven blocking appears to be hardening into standing policy: after the prior-approval requirement imposed on Chinese VPN services in 2017, sweeps like the TLS-tool blocking ahead of the 2022 party congress suggest every major political date now triggers a censorship cycle rather than episodic enforcement.
- If the pattern holds, commercial VPNs become structurally untenable inside China, and circumvention consolidates around open-source, decentralized proxy tools — shifting the arms race from subscription services to protocol design.
The trend: China's censorship is converging on a calendar-driven escalation model, in which each sensitive anniversary brings tighter Great Firewall enforcement and pushes users from commercial VPNs toward stealthier open-source circumvention.
