上海电信 SDN 宽带， tcping 严重丢包， ping 正常，目标 baidu.com

上海电信 SDN 网关（还是十全十美，不是云宽带），周五开始网络莫名其妙抽风，长 ping 百度，基本正常，大概 1W 多个包丢 10 个，但是长 tcping 百度，就会发现丢包率在 30%左右，导致网络几乎不可用。
想求问下板上的大大，我这是被黑名单了么？ PS ，不搞任何 PCDN ，也不养 PT 。
只要 tcping 显示 No response 的时候，电脑微信就会显示网络差或者不可用，b 站视断流，网页也打不开。

打了 10000 号疯狂报修+投诉，师傅上门换了 5 个光猫，局端号称后台刷新、小区对应的光路模块也替换了，但是然并卵，没有任何改善。

看了下，当前网段是 218.81.xxx.xxx 网段，有什么说法么？

tcping 如下：

但是与此同时的 ping 看不出来什么异常
