Network Congestion - Western WA

I am currently having troubles with my home internet during peak hours. The lag spikes and their resolution are in a particular shape that I believe they may be caused by network congestion. We recently had a tech confirm that our coax splitters are removed, seals are waterproof, and Up and Down SNR and power are within expected norms so I can't fathom what else the issue could be. When charting with PingPlotter I can see local network destinations are resolved without issue.

Has anyone else in Western WA (Southeast Of Seattle) noticed this issue between 5-8pm? Any resolution from Comcast?

Hello, @user_cjnfgd. Thanks for reaching our team on Forums regarding the network issues. I know the importance of making sure everything is working as expected. Are you experiencing this issue with multiple devices and are you using a VPN, standalone/personal router by chance?

@XfinityGabby​ I am using a personal router. No VPN though. We have confirmed signal to the street looks good. When I run pingPlotter I can see a specific data center that seems to be the origin of latency spikes and packet loss. Any advice, because this was fixed temporarily but now that I am back from a weekend away it has returned.

Thank you for reaching back out to us @user_cjnfgd! I appreciate you for clarifying you are not using a VPN and confirming this is on all devices. Are your devices experiencing slow or intermittent connections?

All devices are having the same intermittent connection issues. I will attach a picture once I have one but all devices are showing the packet loss and ping variability on the same network node 'be-36131-cs03.seattle.wa.ibone.comcast.net'

I have switched my Gateway from an Arris SB8200 to a G34 that is recommended on Xfinity's website to rude out the cable modem. I am connecting to my computer using an Ethernet Cat 8 cable, the high packet loss and high ping is usually around noon until like midnight everyday and I thought I was dealing with Xfinity network congestion.
Power cycle the gateway/ router did not help.

Below are my modem's downstream and upstream level also a tracert result in a high latency when making connection to google.com
