We confirm that the Great Firewall (GFW) of China has recently begun blocking ESNI—one of the foundational features of TLS 1.3 and HTTPS. We empirically demonstrate what triggers this censorship and how long residual censorship lasts. We also present several evasion strategies discovered by Geneva that can be run either client-side or server-side to evade blocking.

我记得根据现行的 IETF ECH 草案，哪怕服务器端不支持 ECH，客户端也可能会发送一个假的 GREASE extension...那墙要怎么处理，无条件屏蔽所有出国连接么...
