About this network

China Unicom's China169 backbone (CHINA169-BACKBONE) — the second of China's big state-owned carriers, serving fixed broadband especially in the north.

What it's used for

• Fixed-line broadband and backbone connectivity for a very large subscriber base across China.

Notable

• State-owned "eyeball" network; international traffic is subject to China's national filtering.
• Together with China Telecom (AS4134) and China Mobile (AS9808), it carries the bulk of Chinese consumer internet.

Interesting

• China Unicom historically dominated the northern provinces while China Telecom led the south — a split that still shapes domestic routing.
