Under April 2026 enforcement pressure, surviving VPN resellers converged on three strategies: raising prices to cover higher infrastructure costs, switching from transit to direct-connect (higher latency, worse peak-hour performance), or deploying proprietary protocols with dedicated clients — the last option breaking compatibility with standard Clash and Shadowrocket clients and fragmenting the interoperable ecosystem.

The April 2026 enforcement wave against Chinese VPN resellers operates primarily through administrative "reporting + line-cutting" (通报+拔线) mechanisms enforced via Ministry of Industry and Information Technology bulletins, not packet-level DPI changes. Operators report that newly acquired upstream resources are reported and cut with recovery periods described as "uncontrollable," and that upstream providers typically do not refund resellers after enforcement actions.

§一句话结论 / §这轮波动到底发生了什么 policy

China Telecom Group issued directives to Guangdong Telecom requiring comprehensive rectification of cross-border dedicated-line (IEPL/跨境专线) services used for circumvention. Guangzhou launched enforcement first; other Guangdong cities were expected to follow, threatening widespread IEPL line interruptions for providers using Guangdong Telecom as their domestic ingress.

§广东方向专项整治传闻的影响 deployment

China Telecom Group reportedly issued directives to Guangdong Telecom in April 2026 requiring comprehensive rectification of cross-border leased-line (IEPL/专线) businesses used for circumvention, with Guangzhou leading enforcement and other Guangdong cities expected to follow sequentially. The targeting is infrastructure-class-specific (IEPL lines as a category) rather than generalized protocol blocking.

§广东方向专项整治传闻的影响 policy

The dominant enforcement mechanism in April 2026 was administrative 'reporting + line-cutting' (通报 + 拔线) backed by MIIT bulletins, not protocol-level DPI changes. Operators reported that newly acquired upstream resources were reported to authorities quickly after acquisition, recovery timelines were uncontrollable, and some upstream providers refused refunds after enforcement actions, producing sustained capacity contraction across the shared VPN-reseller ecosystem.

§这轮波动到底发生了什么 deployment

Operators facing the April 2026 enforcement wave described three survival paths: (1) price increases to pass on resource costs, (2) switching entirely to direct-connect, or (3) deploying proprietary protocols with dedicated clients — making standard Clash/Shadowrocket clients non-functional for those providers. The commercial forecast is for low-price high-quality plans to disappear and for month-by-month billing to become the default as users hedge against provider collapse.

§5月以后机场可能怎么活下去 deployment

The April 2026 enforcement cycle created a resource-scarcity feedback loop: upstream providers cut lines with no obligation to refund resellers, newly acquired replacement resources can themselves be reported and cut within days, and stable-resource availability windows are described as "越来越短" (increasingly short) while costs rise concurrently. The overall effect is systemic capacity contraction forecast to continue through at least May 2026.

§这轮波动到底发生了什么 / §四月后的趋势判断 deployment

Shared domestic-entry transit architectures (国内入口 + 海外转发) suffered disproportionate impact because all nodes sharing a single domestic entry point went down simultaneously when that entry was reported and cut. Operators described configurations degrading from 'three-line redundancy to single entry,' eliminating failover capacity under enforcement pressure.

§为什么中转机场这次受冲击更明显 detection

Transit/relay architectures (国内入口 + 海外转发) suffered disproportionate impact because multiple nodes share a single domestic entry point: when that entry is reported or cut, the entire batch of nodes fails simultaneously. Operators described this as "三线变单线" (three-line to single-line collapse), with only direct-connect fallback remaining — at higher latency and with worse peak-hour performance.
