They are doing the same thing to my girlfriend and I here in Las Vegas. We never have gone over our data cap but for some reason every single night at about 9:50 pm they throttle our upload and download speeds. The download speed isn't so bad but they often bring the upload speed down to 1 mbps or less. This has been ongoing since September 2017 and I have had so many service reps out here I have lost count. Seriously considering switching to Cox Business to see if this issue would end. Unfortunately Cox has a monopoly in this area and they realize it so they are abusing their customers quality of service!
