腾讯云轻量服务器经常性速率不达标，变成只有1Mbps的网速，受影响地域香港一区119.28.9x.x的ip段
服务器经常性速率不达标，变成只有1Mbps的网速，不知道什么情况，大概5分钟左右又恢复正常30Mbps，一会又突然变成1Mbps，非常影响业务运行，这个问题持续好几个月了，是不是服务器的宽带运营商出问题了？如果更换ip地址，他能否解决速率不达标的问题？不知道有没有遇到相同问题的小伙伴！毕竟服务器只有一次更换ip的机会。
服务器内测速结果如下

然后客服回了一句：中国香港地区IP的网络带宽在高峰期可能存在无法达到峰值、无法保证访问质量的情况
总结：客服说这是正常的，因为这是低价最便宜的机器，想要更好的网络，请购买云服务器搭配精品网，其它ip会出现宽带抢占的情况（超售）。如果这是只在高峰期发生也自认倒霉了，但是这是全天都会发生宽带只有1Mbps的情况持续5分钟才恢复30Mbps。
帖子补充
在QQ群里问了一下，正在使用腾讯云的大家都有这种问题，有人还一直认为是香港到大陆的问题，让他卡的时候测个速，果然有一样的问题被限速到1Mbps。
现在知道了，不是香港到大陆的问题了吧！阿里云就没腾讯云这种现象
