NV - Intermittent latency spikes and packet loss, mostly in the evening
Maybe somebody here wants to see if they can explain what is going on. For months now I have had short periods of poor service almost always in the evening. I have had multiple techs out who could find no issue. I have replaced every piece of equipment on my side of the connection, including the cable modem, at the suggestion of cox support. I have been put on "home monitoring" and been told nothing indicates any of the lines leading to my modem need to be replaced. I sometimes get error messages in the event log of the modem and have corrected/uncorrected packet counts but those do not correspond to the time of these interruptions.
Nobody seems to want to admit there is an issue or seems to get back to me with any information. I started documenting the issue at the end of December here https://www.dslreports.com/forum/r32616178-NV-Intermittent-latency-spikes-and-packet-loss

Reset modem around noon after the first graph but it doesn't seem to matter.

No uncorrectables or event log entries during these periods.

Seems like it has to be usage related. Ingress or congestion that increases as people use it more during the evening? Tech is coming out in the morning.

Hey I just wanted to come here and post that you are not alone. This has been happening quite literally for the past probably 9 weeks in my area of Vegas (Paradise) as well and of course they never find anything wrong. It's beyond freaking frustrating at this point and the only thing they can tell me anymore is 'be patient' because 'they are upgrading the area'. That doesn't help that I maybe have service 30-40% of the time.

Just an update, working with a tech who at least seems committed to figure out what is wrong. Found small amount of ingress on my line and some on one of my neighbors. Replaced the coax run from my dmarc through the attic to the cable modem but no luck. You can see some downtime at 2pm from replacing the cable and then around 4pm we see the issue is still present.
The next day (Friday) the issue was later but quite pronounced for over an hour at around 11pm.
Noise seen from the neighbors line was even less than mine which makes me skeptical removing it will solve the issue but we will see.

The tech I've been working with is great. The tap should be getting replaced within the next few days and will reevaluate after that. Just documenting the plot from 2020-03-18 here:
Yesterday ~11:40am they finished replacing the drop line and issues came back after 1pm.
At ~2:20pm I removed a UPS and any other equipment that was near the modem just to see.
At ~8:10pm I bypassed all networking equipment and ran directly off the modem with a different ethernet cable.
At ~9:20pm I restored networking.
Issues persisted until about 1am when things settled down. The problems are definitely more prevalent during daytime hours and more frequent since people started staying home due to the coronavirus. Working from home during this involves attending teleconference calls which makes this type of performance issue quite apparent.

I had exact same problem for like a week already. I can't even play any game since the high latency hitting my internet so hard. COX needs to do something about this because of this an essential time while most people are staying home and using their internet. I wish I can use another service provider.
