Unable to access certain websites

Hi, I can not access certain websites (almost all websites operated by Sina Corp) via TPG FTTB network. However, I am able to access them by using mobile data or other internet providers' network. I've tried running a Traceroute, but the result was "request time out". Besides, the Huawei HG659 router would not let me change DNS server from TPG to Google. So, I'm not sure if its a DNS Problem.

The websites that I can not access↓

Hi @zack .

TPG and Google agree on ip addresses. It is a routing problem.

www.sina.com, weibo.com, www.weibo.com all timeout in the Soul network, not finding the next hop.

sina.com gets into a routing loop in Chinanet-Backbone.

nslookup command allows you to specify a DNS address.
