Cannot reach any mainland China servers since Oct 24 (traceroute dies after entering China Telecom 202.97.x) - Seattle

Thanks for getting back to me. The Xfinity app shows [no outage or planned maintenance] for my address. There's no error code. Connections just time out: TCP port 443 and ping to mainland China IPs (for example 220.181.38.148, and drive.quark.cn at 203.119.146.35) get no response, and in the browser the page just hangs until it times out. I retested this morning (Oct 31) and it's still failing. Traceroute always stops right after the last Comcast hop (96.110.36.218) once it reaches China Telecom 202.97.x, and China Mobile routes die at 223.120.x the same way. This started on Oct 24 around 5:25 PM PT. Could this please be escalated to network engineering to check Comcast's routing/peering toward China Telecom and China Mobile? Thanks!
