Vultr VPS韩国首尔机房速度和综合性能参数测试

Vultr 商家有新增韩国首尔机房,这个是继日本、新加坡之后的第三个亚洲机房。不过可以大概率知道肯定不是直连中国机房的,因为早期的日本机房有过直连后来取消的。今天准备体验看看VULTR VPS主机商的韩国首尔机房的云服务器的速度和性能。1、全球节点PING速度测试这里先通过PING测试工具看看全球几十个节点的PING速度。看到好像移动速度还不错。2、路由去程测试测试看看VULTR韩国首尔机房的节点...

搬瓦工:香港PCCW机房即将关闭;可免费升级至香港CN2 GIA;2核2G/1Gbps大带宽高端线路,89美元/年

搬瓦工怎么样?这几天收到搬瓦工发来的邮件,告知香港pccw机房(HKHK_1)即将关闭,这也不算是什么出乎意料的事情,反而他不关闭我倒觉得奇怪。因为目前搬瓦工香港cn2 GIA 机房和香港pccw机房价格、配置都一样,可以互相迁移,但是不管是速度还是延迟还是丢包率,搬瓦工香港PCCW机房都比不上香港cn2 gia 机房,所以不知道香港 PCCW 机房存在还有什么意义?关闭也是理所当然的事情。点击进...
