CloudCone 新增洛杉矶优化线路 年付17.99美元且简单线路测试
CloudCone 商家在以前的篇幅中也有多次介绍到，这个商家也蛮有意思的。以前一直只有洛杉矶MC机房，而且在功能上和Linode、DO、Vultr一样可以随时删除采用按时计费模式。但是，他们没有学到人家的精华部分，要这样的小时计费，一定要机房多才有优势，否则压根没有多大用途。这不最近CloudCone商家有点小变化，有新人洛杉矶优化线路，具体是什么优化的等会我测试看看线路。内存CPU硬盘流量价格...
Linode（$5/月），新用户注册送100美元,11个数据中心云服务器

UCloud新人优惠中国香港/日本/美国云服务器低至4元
