China Isolates Itself From Worldwide Web For Over an Hour

A complete shutdown of encrypted web traffic isolated China from the global internet for 74 minutes Wednesday morning, blocking citizens from accessing foreign websites and disrupting international business operations that depend on secure connections to offshore servers. The Great Firewall began injecting forged TCP RST+ACK packets to terminate all connections on port 443 at 00:34 Beijing time on August 20, according to activist group Great Firewall Report.

The standard HTTPS port carries most modern web traffic, meaning Chinese users lost access to virtually all foreign-hosted websites while companies including Apple and Tesla couldn’t connect to servers powering their basic services. The blocking device didn’t match known Great Firewall hardware fingerprints, suggesting Beijing either deployed new censorship equipment or experienced a configuration error. No significant events requiring information blackout occurred during the outage window. Pakistan’s internet traffic dropped significantly hours before China’s incident, potentially connected through shared firewall technology.
