I hope to get some help as well following this because I am also in Arizona, Mesa AZ actually but maybe my signal/connection issues are similar in nature.
We are experiencing multiple daily outages that only last a few minutes each time. Between 5min to 15min each time, multiple times a day. It has been about 2 weeks since this started happening according to my roommates. Only today evening I started logging these random blackouts trying to notice a pattern. So far every 40 to 60 minutes they are occurring. We do have multiple smart devices but besides these past 2 weeks things were working out fine, some outages here and there but those were mainly documented as general service outages on Cox's side. These recent ones are quite noticeable and too frequent to just ignore to be honest. We even went and bought a new router set up, Netgear's Orbi mesh router, to see if our older router might have been the issue and nothing :/ Other than us finally getting better speeds when the service works, about 900Mbps down and 35Mbps up, the issue seems to persist. We had a tech come over this past Sunday and she removed some filters and according to her, changed some connections on the line outside our home that was stripping due to weathering. After that we still have the same random drop of service. What I notice is when it feels like a shortage is comming i try to run a speed test and see what it does and see download speeds around 50Mbps and uploads in the decimals! 0.27 Mbps this last time i tested. We have tried resetting routers, modems, etc to no avail. Other than that I have to just wait for the service to resume. I also try to check our account when it does happen just to make sure Cox's service is not down for some reason but every time this happens our account indicated our service has no issues.
Really hope someone from Cox sees this and gives us some idea on how we can get it fixed. I feel like an idiot having to call for a technician every time for them to show up and this never happening while they are here so idk where else to turn.
Just as a summary today June 8th I have logged there outages:
7:33 - 7:40
Connection went out again for a couple of minutes.
8:33 - 8:35
Connection went out again for a couple of minutes.
9:16 - 9:18
Connection went out again for a couple of minutes.
9:25
Connection is fluctuating. Speed test showed Download 51.85 Mbps and Upload 0.27 Mbps. Earlier today Download was at 895.75 Mbps and Upload 34.45 Mbps
