腾讯云轻量服务器两款低价年付套餐 2核4GB内存8M带宽 年74元
昨天，有在"阿里云秋季促销活动 轻量云服务器2G5M配置新购年60元"文章中记录到阿里云轻量服务器2GB内存、5M带宽一年60元的活动，当然这个也是国内机房的。我们很多人都清楚备案是需要接入的，如果我们在其他服务商的域名备案的，那是不能解析的。除非我们不是用来建站，而是用来云端的，是可以用的。这不看到其对手腾讯云也有推出两款轻量服务器活动。其中一款是4GB内存、8M带宽，这个比阿里云还要狠。这个真...
SugarHosts糖果主机,(67元/年)云服务器/虚拟主机低至半价
SugarHosts 糖果主机商也算是比较老牌的主机商，从2009年开始推出虚拟主机以来，目前当然还是以虚拟主机为主，也有新增云服务器和独立服务器。早年很多网友也比较争议他们家是不是国人商家，其实这些不是特别重要，我们很多国人商家或者国外商家主要还是看重的是品质和服务。一晃十二年过去，有看到SugarHosts糖果主机商12周年的促销活动。如果我们有需要香港、美国、德国虚拟主机的可以选择，他们家的...
