魔方云旗下的子品牌：cubecloud，它香港的机房也使用CN2线路，而价格与配置也与我之前使用的相差无几，所以最近进行了测试与观察。
因为是国人开设的平台，我想是出于保护IP资源的缘故，禁止假设任何违反国内法律的服务，这也能理解，相关内容如下：
另外，因为香港机房带宽资源和费用的缘故，上下行带宽分别被限制在50Mbps左右，而且禁止提供大流量服务。如果长时间占用带宽，极有可能会被短时禁用或者永久禁用。
以下测试的时间均为中午时分。
我写这篇文章的时候，香港节点有以下套餐:
而我选用“香港BGP – 1G”套餐用作测试。
详细配置如下：
经过检测发现宿主机所用的CPU与描述中的一致，为：
因为我有2颗vCPU核心，所以拥有5.2GHz。

长ping测试共计发出15852次ping，收到15791次回应，丢失61次，接近0%丢包率。我在深圳，ping延迟均值为19ms所有，属于正常值。
wget下载测试分为2部分，分别从我家里下载文件与从服务器下载文件，而服务端下载的文件为vultr.com的1gb测试文件：

上行速度为5.7MB/s，也符合标称带宽。
50Mbps的网络速度在香港机房是非常可怕的，不知道长时间占用多长时间会被服务商封禁。

因为我家宽带禁ping，所以第11跳到我家是超时，我并没有放上来。从第3跳开始到第8跳均为CN2线路，先到达广州在到深圳。以下为我家到服务器的追踪结果：

经过5次dd命令的测试发现，速度在220MB/s左右，这个数值肯定是经过限制的，但这也能理解，速度完全能接受。
