Latency within Asia is relatively low, while US and European latency remains within normal expectations.
8. Mainland China Outbound Routing Analysis
China Telecom Outbound Route
Telecom route:
China Telecom → 202.97 → Hong Kong → Target Server
This uses the traditional China Telecom 163 international backbone to Hong Kong.
China Unicom Outbound Route
Unicom route:
China Unicom AS4837 → Hong Kong → Target Server
China Unicom enters Hong Kong quickly with relatively low latency.
China Mobile Outbound Route
China Mobile route:
China Mobile → Guangzhou → Hong Kong → Server
The routing path has relatively few hops and maintains good latency control.
9. Mainland China Return Routing Analysis
Return routing is one of the most important indicators of line quality.
China Telecom Return Route
Hong Kong → CTGNet → CN2 Backbone → China Telecom
This is effectively:
CTG (China Telecom Global premium route)
China Unicom Return Route
Hong Kong → China Unicom 10099 → China Unicom 4837 → Mainland China
This belongs to:
China Unicom 10099 optimized routing
China Mobile Return Route
Hong Kong → CMI → CMNET
This is:
China Mobile CMIN2 optimized routing
Overall return routing structure:
| Carrier | Return Route |
|---|---|
| China Telecom | CTGGIA |
| China Unicom | 10099 |
| China Mobile | CMIN2 |
This is a classic Hong Kong three-network optimized routing combination.
10. YouTube Speed Test Performance
Local network:
China Unicom
YouTube Stats for Nerds results:
- Connection Speed: 371022 Kbps
