Bilibili CDN 广东电信烂了两天了

工单节点使用指南

• 请用平和的语言准确描述你所遇到的问题

• 厂商的技术支持和你一样也是有喜怒哀乐的普通人类，尊重是相互的

• 如果是关于 V2EX 本身的问题反馈，请使用反馈节点

根据测试结果看，可能是广东电信到 CDN 节点的 TCP 路由问题。

不过这个调度很奇怪，使用运营商分配 DNS 情况下，广东省还要跨省调度，又不是什么 IDC 资源匮乏的地方

说句题外话，不要用一些奇怪的 CDN，开了大会员看视频，码率增加后，奇怪的 CDN 速度太慢反而导致体验更差了。

bb 站的 cdn 常年毛病不断。我在海外经常莫名其妙一阵子一阵子故障。
要么直播卡疑生，或者视频卡疑生。这个好了那个又坏了，高清不卡了大会员卡，大会员不卡了追番卡。
而且 iOS 上常年拖动就卡。方法试尽最终全看脸。b 站跟度盘，是唯一把我养成对网速看淡的地方。
尽管除了这俩，访问其他世界任何角落都能充分跑满我的 10g 光纤。

会时不时的切过去，不仅这个域名，还有 s1/s2.hdslb.com 啥的乱七八糟一大堆域名。
只要有一个有问题，页面显示就出问题了。
