昨天下午5点左右，alienvps的ufo1挂了，开了最高优先级的ticket，居然这么大半天过去了没人回，估计是过圣诞去了，好吧，你们玩好。我从来不会因为服务差或者客服差要求charge back，这次看来是得给他们点教训了。
Fuck off! alien vps

说说alienvps
上次在wht看到alienvps的openvz促销，256内存只要4刀一个月，就搞了个拿来做后端，结果烦心事不断
ps:这里所谓烦心事都是真实发生的物理状况，绝非个人感觉
首先，vps在我12月4号付款以后是可以自动开通的，可惜开通以后给分配到了一个不能访问的ip（不是撞墙，而是根本就是down掉的ip），写ticket过去，46分钟后给换了新ip，开始正常访问
好景不长，12月7号，ip再次down掉，写ticket过去，4小时后回复了“your VPS will be back online soon”，6小时候，换上了新ip，解释说他们有个ip段有问题，而我刚好受影响，给了承诺“Your IP will not need to change anymore.”。
这次折腾以后，稳定了很长一段时间，一直到大概一周前，我发现内存还剩一半没用的时候，就不能启动新进程，直接报错内存不足，于是写ticket问，结果居然过了两天没答复，结果我自己google到了答案，要求他们协助，更改privvmpages和shmpages的值，这一等就是5天，我也没抱任何希望了，反正到期就move，结果昨天（20号），有回复了，说已经调整了，结果我冲上去cat /proc/user_beancounters ，看到的那两个值依旧是65536.
以上这些都还算温柔，最生猛的在下面。
一小时左右前，我正在shell上编辑文件，突然就看到系统即将halt的广播消息，我想可能只是他们要重启下服务器，就没管，过了5分钟，依旧不能登陆回去，就冲到panel看，服务器状态正常，以为又是什么抽风bug，就手动重启了，结果已经不能登陆。
然后就小小的试了试ping，结果：
92 bytes from 209.188.5.226: Time to live exceeded
Vr HL TOS Len ID Flg off TTL Pro cks Src Dst
4 5 00 5400 19c8 0 0000 01 01 7ec6 192.168.1.3 184.171.166.196
从来没看到过ping是这样的结果，就很好奇的traceroute了一下，结果看到包在两个ip之间跳来跳去，直到ttl- –

然后再去看panel，发现ip居然变了，然后邮箱就收到信了：“We apologize for the inconvenience, we have new IP space and have no choice but to change the IP address of your VPS.”
够简洁明了吧？靠，居然可以这样不负责任的突然换掉一个跑了半个月多的vps的主ip也是唯一一个ip，幸好只是个后端，只需要在前端稍微改改配置就可以恢复访问，不然，就是好几个小时的downtime了
不过因祸得福，新ip网通走的是比较nb的nlayer线路，电信走xo，原来ping要350左右，现在居然降到了250左右，电信更nb，只有190，和直连网通的xeex有的一拼
不过，这样的服务商，还是躲远点好。。说不定什么时候再给你换个ip，气死你
cs说了一句很无语的话：Thanks for bearing with us as we are still learning the ropes.好吧，你们慢慢折腾，我先走了
几只VPS的Unix Benchmark跑分结果
最近在选择vps上折腾的很惨，还遇到莫名其妙的数据丢失，幸好有backup，只丢失了不到3天的数据，今天有点时间，就把自己能控制的5只vps拖出来遛遛，跑了下分。
