With the convening of the two sessions, the massive blocking of the Great Firewall has arrived as promised. The blockade has been in place since the morning of the 4th.
Unlike the previous blocking of foreign IPs only, GFW will also block outbound connections from within the country in this blockade. It is speculated that because of the highly symmetrical nature of transit machine traffic, firewalls can easily identify these transit nodes and block them.
Several merchants engaged in related businesses claim to have stopped their services due to the blocking of outbound connections to their transit servers. Since the firewall uses a traffic analysis model, it is ineffective in this case regardless of the protocol used.
