This appears incredibly consistent with 'high average use' timeframes. I noticed internet service was generally fine after around 1am- at around 7am to 9am it starts to act up again. This is consistent with everyone working from home/now using their internet far more than they used to.
I just don't think many ISPs in America were ready for this kind of incident. Europe has a much tighter infrastructure- one can argue America is more spread out, but infrastructure in the main cities have no excuse.
btw I would recommend trying alternate speed tests; Cox uses speedtest.net and ONLY connects to their own servers. Incredibly, I've started to get much worse results from their test servers. I will literally reach max speed faster on a further server owned by Sprint or someone else than by their testing ones. So just try speedtest.net on a different server than cox's default or dslreports or something.
According to cox they were ready for the demand. LOL
