findings extracted from this paper
-
LetsVPN's exit is described as part of a broader pattern: a wave of 'airport' (proxy subscription service) outages across multiple providers in April 2026, documented in a companion article titled '2026年四月份各大机场断线详解,' indicating coordinated or systematic GFW blocking affecting the circumvention ecosystem broadly during this period.

Two documented enforcement actions against VPN users were reported in April 2026 in China: one user was summoned, given a warning, and fined 300 RMB for using LetsVPN to access foreign platforms; a second user in Dalian was fined 500 RMB on April 2, 2026 for using 快喵VPN to log into Telegram.

The blog author, drawing on evaluation experience, concludes that LetsVPN's failure was not caused by IP exhaustion or ordinary node instability but by precise protocol-signature identification: once the GFW extracts a client handshake feature, it can simultaneously block all connections sharing that signature across hundreds of thousands of users.

LetsVPN permanently exited the Chinese mainland market in late April 2026 after its technical team spent 20 days making hourly adjustments and confirmed it could not restore connectivity. The official announcement designated April 8, 2026 as the effective service-termination date and initiated a full refund program.

The article documents that large-scale 'one-click' commercial VPN providers with static protocol stacks have become effectively non-viable in China, while subscription-based proxy node services using open-source clients (Clash, Shadowrocket) with server-side rapid IP and datacenter switching demonstrate substantially greater resilience to GFW blocking waves.
