AlphaRacks 家的主机相当便宜，之前就买过他们家的 OpenVZ 主机，$10 一年的样子，但是速度真的很慢，搭梯子也就只有每秒几百 KB 的峰值，可见其超售确实严重（100% 不推荐购买）。向客服申请退款后，他们只是将金额退还到了我的余额里，最近他们给我发促销邮件表示，提供 $15 一年的 KVM 主机，想到反正那笔钱也取不出来，于是就买了台试试。
价格：15 刀 1 年
虚拟类型：KVM
机房位置：洛杉矶
其他信息：已开启 BBR，未购买其 1GbPS 的宽带加速包

结论
可以看到 KVM 机型的网速还是相当不错的，$15 的综合性价比毫无疑问属于中上水平，值得购买。但是我还是要忍不住再啰嗦一句，不要购买他们家的 OpenVZ 机型，超售严重，网速极慢。
