The recent crackdown on cross-border networks in April is on an entirely different level compared to previous routine measures.

From the internal notifications issued by the three major telecom operators recently, the strategy of the GFW this time is to directly cut off connections. As soon as any violations are detected involving cross-border dedicated lines or VPN nodes, there will be no grace period for rectification; instead, server ports and network connections will be directly severed.

This is undoubtedly a huge pain point for those relying on overseas development resources. Now, maintaining a stable connection to the APIs of GPT or Claude to assist in handling complex code logic, or trying to circumvent local model review restrictions to test the limits of AI reasoning, has seen a dramatic increase in maintenance costs and risks.

Many enterprise-level relay nodes that previously operated smoothly have also unexpectedly shut down in recent days. When the official measures against circumvention escalate from "interference" to "direct physical disconnection," the originally established technical architecture is always on the brink of random failure.

As the trend of building higher internet firewalls continues, the tech community is forced to spend a lot of time searching for more covert communication protocols. This forced information isolation is likely to begin to ferment the long-term damage to the overall technical ecosystem and development efficiency.
