Packet timeouts at edge routers
Traceroute shows timeouts once packets hit, what appears to be, the edge routers.
So, after 96.110.33.202/96.110.33.206 nothing returned.... after 68.85.176.113 nothing returned.... after 96.110.33.194/96.110.33.198/96.110.33.206 nothing returned.
A traceroute to `youtube.com` will timeout on what appears to be the edge hop, but pick back up the next hop (see image):
Generally, it appears that whenever it hits an edge router, responses time out. This has caused... lots of issues. Things timing out, latency jumping, web pages not fully loading, VPN dropping, etc... For the youtube.com traceroute every router in between returns on a usual day (PITA if you do block ICMP for exposed routers... really).
Normal traffic on network looks fine... it's just once you try leaving the network from any peering point that it starts going haywire. Some peering points are better than others.
Are there any known issues? I've rebooted cable modem and home router just incase there was some stupidity with on network transfer and authenticating instead of just getting connected to the network.

The trace continues past the timeout at the intermediate hop and reaches the destination, so the timeout is probably not significant. Please see https://www.dslreports.com/faq/14068.

Are you connecting via Wifi or Ethernet? If Wifi, it's best to switch to an Ethernet cable connection if possible for testing. That would allow you to determine whether the problem is the Wifi signal or the link between your modem or gateway and Comcast's network. Network connection problems that affect both Ethernet and Wifi devices are often due to poor coax connections or damaged coax cable, usually in or near your home. Running the cable through a surge protector, a defective splitter, or too many splitters can cause signal problems as well. If there is an amplifier in the line make sure it's getting power.
If you want to troubleshoot this yourself, please see Internet Troubleshooting Tips. If you still need help, please post your Internet plan speed and the following information from your modem or gateway (from http://192.168.100.1 or http://10.0.0.1):
If you can't find the problem or you'd rather have Comcast take care of it and an employee does not respond to your message here, call them at the phone number on your bill or 1-800-Comcast, or use one of the options on https://www.xfinity.com/support/contact-us/. It's not likely they can fix the problem remotely. If not, insist they send a tech out to identify the cause and correct it.
If the tech finds bad coax, splitters, amplifiers, or connections in your home (even if Comcast originally supplied them) you'll probably have to pay for the visit ($70-$100) unless you have their Service Protection Plan ( https://www.xfinity.com/support/articles/service-protection-plan, closed to customers that don't already have it). If the trouble is due to a faulty Comcast rental device or anything outside your home you shouldn't be charged.
