前几天DO在微博上发布消息说本周有惊喜,原来这惊喜就是新加坡数据中心的开放。
我马上新建了一个新加坡的VPS试用了一下,体验结果不是很令人满意。整体上说,性能还是不错,UnixBench的结果有885.5分,下载速度和I/O都还是不错的,但是可能是路由上的问题(我的猜测),ping值时高时低,低的时候80ms,高的时候几百毫秒,并且掉包很厉害。我从美国机房的服务器wget这个VPS的数据,速度可以达到14.5MB/s。个人觉得这样的VPS还不是很适合我们中国用户。

题外话,这样的VPS拿来做VPN还是不错的,价格比较实惠,并且不怕DigitalOcean无故删除你的VPS,删了之后再搭建一个VPN即可。
