如果你家是移动宽带，挑 VPS 要特别看「CMI」。
一句话解释
CMI（China Mobile International，AS58807）是中国移动的国际精品网，移动用户回程走它体验最好。
特点
- 移动宽带用户回程首选，延迟低、晚高峰相对稳。
- 电信/联通用户走 CMI 体验一般，不必专门追。
- 移动出海近年改善明显，CMI 机型越来越多。
适合谁
本地是移动宽带的用户。三大运营商里移动出海曾是短板，CMI 是针对性的解法。
提醒
线路好不好要对应你自己的宽带运营商——别人说 CMI 好，但你家是电信，意义不大。电信看 CN2 GIA，联通看 AS9929。

If you’re on China Mobile broadband, CMI is the one thing to look for when choosing a VPS.
In a Nutshell
CMI (China Mobile International, AS58807) is China Mobile’s international premium network. Mobile broadband users get the best return-route experience when traffic runs through CMI.
Key Characteristics
- Top pick for China Mobile users on return routes — low latency, relatively stable during evening peak hours.
- Telecom / Unicom users on CMI get average performance — not worth chasing specifically.
- Mobile’s international connectivity has improved significantly in recent years, and CMI-based VPS options are increasingly common.
Who Is It For?
Users on China Mobile broadband. Mobile’s international routing was historically a weak point among China’s three carriers — CMI is the targeted fix.
Reminder
Whether a line is good depends on matching it to your own ISP — if everyone says CMI is great but you’re on Telecom, it won’t matter much to you. Telecom users should look at CN2 GIA; Unicom users should look at AS9929.
