I block traffic in/out of my home network by geographic location of the remote endpoint. I was having a lot of problems trying to login to the forums and eventually realized that jquery wasn’t being loaded. The URL to retrieve it was https://cdn.bootcss.com/jquery/3.3.1/jquery.min.js. This request was being blocked by my firewall rule. I looked up the IP that the hostname was resolving to; 126.96.36.199 (for me, I realize this is a CDN) and ran a search on arin.net. Sure enough, Chinese registrar.
I then ran a traceroute and sure enough, see the route traversing to China.
Am I off-base here, or is there something potentially fishy?
