This started at 10 am this morning. It was ok before that. Websites won't load.
I know this won't help you, but at least you have some comfort in knowing it's not just you. It's likely everyone who has Cox internet.
I've been suffering from the same absolutely horrible internet connectivity issues as well for nearly the past 2 weeks. Every single night straight for the past week it's been like that here in Cleveland Ohio area.
I normally don't run speed tests unless I see extreme buffering on streaming or inability to use the service to connect up to work. When I can feel and experience the issues is when I run the speedtests to check if it's really an issue. I'm on Gigablast tier. The cable modem signal levels have been fine in my situation.
I normally get sustained 940 mbit/s download and 35 mbit/s upload, but tonight has been as pathetic as yours. A rather anemic 61 download and 0.31 upload.
Thank you Cox for fixing the extreme noise issue in my area, plus other damaged hardline connections leading to my condo complex from the main street. I saw a bucket truck near a hardline drop down the street from me and bang, my signal issue was fixed. I don't think node overcrowding was my issue. It was a whole lot of damaged connections outdoors and in, which were causing microreflection noise in the whole network. MER (went down to 32) was suffering when the noise would show itself. I don't think it was node ovecrowding in my case.
As you can see from the previously attached screenshot, the speeds were 940 mbit and 35 mbit before the Cox infrastructure took an unexplained dive in quality.
Everything is hard wired gigabit connections, PC to Router to Cable Modem. I've had no issues for years on end until around 1.5 - 2 weeks ago. The modem signal levels are fine.
