@trackrat2 Tech came by today and basically said the same thing to me. He confirmed he's spoken to multiple people in my area as well, and indicated that Comcast was aware back in January that the node was approaching capacity and filed permits for construction on a new node. COVID has not only made the issue worse, it also delayed starting that construction. He said currently this node is by far the worst in all of SW Washington.
The outages in the area last week were them trying to add a 5th channel to the line as a temporary band-aid to the situation, but some of the equipment had issues with it, so they had to roll it back and replace a lot of it. He said next week they are scheduled to turn on the 5th channel again, which should add some relief while they work toward getting the permits with the City of Vancouver on the new node.

@trackrat2 I see good signals and great latency with low jitter in the mornings, and then it degrades and gets unmanageable from about 3-4pm until midnight.
I get about 2-3 T3 timeouts per day, so it's not like its constant. I tried temporarily upgrading to the 1 gig plan so the upload speeds would be better, but it hasn't changed much. Really points to noise or congestion on the line. It also just kind of comes out of nowhere sometimes. Tonight, I'm about 3-4% packet loss (which with the high jitter still makes gaming or VOIP conversations nearly impossible), but then it'll shoot up to 20% out of nowhere for several minutes.
Hopefully I can get the tech tomorrow to see the issue so the Grey Hawk can fly again.

As far as I'm aware, the 2nd hop is the first time it hits Comcast's network though, so pinging out from a computer, the first hop is your networking equipment, then to the street. If you experience 20% packet loss between the first and second hop like I do, then something is very wrong imo.
Getting T3 and T4 timeouts multiple times per day is not symptomatic of a strong, stable connection, I don't care what anybody says. I'll post back what the technician says when they're out tomorrow.

@trackrat2 Would you post the link that you used to get the process started? I'd like to register a similar complaint. Is it https://fortress.wa.gov/atg/formhandler/ago/ComplaintForm.aspx? Judging from your maintenance and outage windows for the past 3 weeks, we're likely in the exact same area/neighborhood because it's been the same for me.
I have a technician coming out (again) on Friday. Like last time, I'm sure they will just claim my signal is strong and within spec, even though I get multiple T3 timeout errors every day and traceroutes that have periods of 20-30% packet loss on the upstream signal.

Bump.
I've gone through all the troubleshooting recommendations on the forum, including even purchasing an entirely new cable modem and router instead of the Xfinity-provided one, replacing coax and ethernet cables, the wall socket, and lone splitter outside my house.
Issue still happens constantly, and only really manifests itself on my upload. I finally got support to send me a tech this Friday, so we'll see if they are more helpful than the last one. Will reply here with results.

For months now, I've been trying to get connectivity issues resolved with Comcast support, with no resolution in sight. My modem logs are just filled with errors like these:
"Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=14:c0:3e:06:65:89;CMTS-MAC=00:cc:fc:61:33:21;CM-QOS=1.1;CM-VER=3.1;"
"RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW;CM-MAC=14:c0:3e:06:65:89;CMTS-MAC=00:cc:fc:61:33:21;CM-QOS=1.1;CM-VER=3.1;"
"Dynamic Range Window violation"
I frequently get long periods of 20% or more packet loss on the upload that basically makes it impossible to carry on a VoIP conversation or conference call, which is basically most of what I do for my job.

Any help would be greatly appreciated because I feel like I've exhausted every endeavor I've tried, from phone calls, daily/nightly chats, multiple outage resolutions and maintenances in my area, and even a tech visit, where he confirmed everything from my house to the street looked good.
Any help would be appreciated.

@Gorgon12345 Don't blame you. I'd go to Ziply in a heartbeat if it was available in my area. With any luck, they'll expand their service territory and I can finally drop Comcast.

@trackrat2 Wow, I had the exact same thing happen tonight and I live in Vancouver as well. As of right now, I'm down to about 2% PL but I had easily 20-25% for about a solid hour or two. It was completely unusable even to stream video, let alone something that required a constant steady connection.
I also have a scheduled maintenance in my area slated for 1:00 AM on Wednesday. Wild.

Just wanna say, you're doing gods work here. I live in Vancouver, WA and get the same issues. Last week's maintenance in my neighborhood made it a little more manageable, but I still frequently get periods like this https://imgur.com/a/9cxLOWF that make it nearly impossible to attend a video conference during the day or game at night.
I can't recall how many times I've been on chat or phone about the issue, but it's starting to get real, real old.

@RobertWy No it's not.
I literally explained the problem, and I've gone through all the troubleshooting steps in this link. It's not the usual "check your cables" situation since this only happens in the evenings, every single night.
I can only assume I now live in a neighborhood with high-usage neighbors and the throughput is terrible at night because of it. If that's the case, is this something that Comcast will eventually fix in peoples' experience or will I be forced to go to another provider? I'd like to avoid spending weeks of the end-around with Xfinity if they won't do anything in this case.

I've moved into a new neighborhood and am on a 300 down / 10 up internet package. During the day and early morning, I see solid service. However, by around 4pm until the late evening, it basically turns to this every night:
https://imgur.com/a/EWZXV1N
I've gone through voice chatting with an operator, text chat multiple times, seen the script they try to run through with you to troubleshoot. It's not an issue with connection to the house, a tech was just out when I moved in to refresh all the connectors in January, and I've been out to look and everything looks fine. Plus, it's just about perfect during the day.
I'm looking for a bit of light at the end of the tunnel here. Does anyone have experience with Comcast actually solving an issue like this on their end, whether that's at the neighborhood node level or further upstream? Worried that my only recourse is to drop Xfinity and go with a slower, hopefully more stable connection in CenturyLink, which has 100 mbps FTTN in my area.
