On August 20, the “great firewall” of China, the Internet control system in the country, for 74 minutes completely blocked the traffic through the standard HTTPS port 443, the GFW Report website tracking the work of the Chinese network reports.
TCP port 443 is usually used for secure Internet connection (HTTPS), which prevent interception and intervention in the data. However, the anomaly affected only this port, while other ports for the Internet and SSH worked normally.
Earlier, China has already limited access to secure formations, but then all the ports and protocols of TLS/HTTPS were blocked. This time the situation was limited to only one port, which is unusual, according to experts.
GFW Report notes that the device that caused the failure does not coincide with the well -known devices of Firevol, perhaps this is a new device or old, working in non -standard mode.
