这是一次计划外订购。陆续记录使用这个Xen VPS的情况。初始印象是它的控制界面比别的VPS正式些，全部web操作。另外每月1000GB的流量很诱人。具体配置如下：
月付: $4.94
内存: 256 MB
swap: 512 MB
硬盘: 5 GB
带宽: 1000 GB
印象：
- 从debian在美国的服务器下载软件包比较慢，大约是100K左右的速度。我用的onexenvps和vpsvillage从Debian源下载速度超快。其中vpsvillage有自己的debian源。
- 自己的页面介绍是股份公司，意思是和那些个人运行的VPS划清界限。
- 控制面板是我所见过的最好的，控制很方便。流量、日志等内容一目了然。
- 北京时间20：50分左右，给对方的客服发了一封信，询问是否自动续费。对方10分钟内回复，说是不会。效率赞一个！
- onexenvps.com似乎很不稳定，有时客服反应极慢，它的网站也极为初级，有时不能访问某些页面。
