Cannot reach certain websites
About a week or so ago, I noticed I could not reach certain websites when connected to my comcast network, but I COULD reach them via a VPN through that same network, and also through my Verizon cellphone or hotspot.
The details:
- I own the hardware: Gryphon router and a Netgear CM500 cable modem
- Confirmed that multiple devices in the house cannot reach the websites when on the Comcast cable network
- Those same devices CAN reach the same websites via a VPN or on a cell network/cell hotspot
- I am not a network engineer
- tried Comcast customer service, who shunted me over to Netgear, who wanted to charge me $130 for tech service. I don't believe either tech understood what I was saying.
I am a little handy, so while on the comcast network I did a traceroute on the sites that don't work. Here is one of them:

According to whois.arin.net, 96.216.180.114 belongs to Comcast Cable Communications, LLC (CCCS).
Here is a traceroute on a second website:

On line 10, whois.ripe.net tells me 62.115.54.21 is located in Sweden(?). I am in the midwest of USA, connecting to (in this case) a server out in (I think) Utah…the hosting company is Bluehost.com. Why would the request be routed that way?
It seems like a DNS problem in the Comcast network, but again, I'm not a network engineer. I don't see how this could be caused by either my router or modem.
Thoughts?
