I've had similar issues --- although mine are more.... erratic. We've had known outages in the OKC area the past two days (well, since last week actually, but 3 outages in the last 24 hours as they've been tracking down a problem).
Right now, I'm getting a decent 400 MBps down and 40 Up --- which is about 45% of my normal d/l speed.
But...in an hour I might check, and have 30 MBps down and as little as .2MPbs up (yes, .2).
I've taken to running the speed test hourly (or more) and the results are completely erratic.
Strangely enough, I got a text this AM that outage in my area was cleared (it came in at 730 or so, but I didn't get it until 830. I immediately rebooted the modem and computers, Amazon devices, etc. None of my hubs/smart speakers could connect, computer was getting about 30down/1 up.
Got on the phone w/ customer service, and about time my call was taken in the queue, I ran a test and had a near perfect 930/40.
Before end of call...it was at 20 and .01 again.
They acknowledge difficulties in the area, and it was supposed to be back up by afternoon.
Afternoon came (w/ no text, I might not have opted in this time), and I rebooted and tested....and...it was terrible.
I ran maybe 10 tests in an hour....and it ranged from 400ish up/10 down to 30 up/.3 down --- and just about every range between.
Got on the chat advisor to talk to a tech --- as I couldn't find (on the website or on the app) whether the outage was cleared or not -- the outage check link just recycled to the tech support page w/o displaying any info.
They stated the service was (apparently) restored, although stated also that the techs might still be working. ??????
As of now, I've had a moderately stable connection...but at only about 1/2 my normal speeds.
Will be contacting them again tomorrow if it's not back to normal..... this up/down isn't helping out the whole "work at home" thing.
I'm in Norman,Okla and I am experencing the same here. I went on a week long test and found it to be that the heavy times it is just like this. I don't think Cox has the capacity that they thought they did.
I am also sure it will get better,but it will take time.
I also have gigablast service.
