首先向讲解下 阿里云cdt 是什么东西。
背景知识：
- CDT (Cloud Data Transfer) 其实是阿里云的一个产品名称，类似于流量包，流量额度。每月免费发放200GB境外流量和20G境内流量。
- 阿里云香港机房直连大陆，效果很棒。具有隐形优化。
低价 (5元) cdt 机器如何组建：
- 临时创建一个OSS对象存储，并且上传Alpine系统镜像文件。
- 创建自制系统镜像，删除OSS。
- 创建一个最低配置的长期抢占式实例，使用自制镜像，2G系统盘。
- 不要选择1小时销毁
- 不要分配公网ip
- 选择2G系统盘，自动备份等功能通通不要
- 不要配置sshkey或者密码，选择创建后再配置。
- 去EIP处开通一个公网ip，并立即绑定到刚刚创建的实例上。网络选择普通多线BGP，不要选择精品BGP。
- 去实例控制台，通过VNC安装系统。
注意事项： cdt流量正价很贵。逼近限额建议立即关机。
晚高峰香港还能跑满这个速度，实在令我倒吸一口凉气。

Wed Sep 9 09:32:54 PM CST 2026从路由上来看，和普通香港直连相比，少了很多跳。我觉得可能类似阿里云自己的“冷土豆”网络。 而且教育网下，也没有绕京之类的。

流量很贵，其他脚本就不跑了。
在刷信息流的时候，没办法和巅峰时期的云途香港精品一样极速秒开。但是已经能日用了。而且云途近期网络劣化，当下两者半斤八两。云途等会不续费了，呵呵。 我的评价是，阿里云cdt可以秒杀其他所有25元以内的香港产品（更贵的我也没买过。。。）
