我们先普及一下常识吧,每年9月的第一个星期一是美国劳工节。于是,有一些服务商会基于这些节日推出吸引用户的促销活动,比如RackNerd有推出四款洛杉矶和犹他州独立服务器,1G带宽、5个独立IP地址,可以配置Windows和Linux系统,如果有需要独立服务器的可以看看。第一、劳工节促销套餐这里有提供2个套餐。两个方案是选择犹他州的,有2个方案是可以选择洛杉矶机房的。CPU内存SSD硬盘配置流量价格...
CloudCone 商家在以前的篇幅中也有多次介绍到,这个商家也蛮有意思的。以前一直只有洛杉矶MC机房,而且在功能上和Linode、DO、Vultr一样可以随时删除采用按时计费模式。但是,他们没有学到人家的精华部分,要这样的小时计费,一定要机房多才有优势,否则压根没有多大用途。这不最近CloudCone商家有点小变化,有新人洛杉矶优化线路,具体是什么优化的等会我测试看看线路。内存CPU硬盘流量价格...
