This is a collection and summary article of VPS hosts and computer rooms currently connected to CN2 lines. The main reason for initiating this article is that Alibaba Cloud, Classic VPS, etc. have launched CN2 line hosts. After purchasing and experiencing it myself, I found that the download speed of CN2 line VPS hosts can almost always be above MB/s, and the routing packet loss rate is very low. This has greatly changed my impression of foreign VPS.
