Oct 5th through Today

Is Cox Cable having issues or maintenance going on late evenings this week?  

Between 10pm and 12am (maybe later, but this is bed time), multiple times this week my service drops to 0.1 mbps download and 5.0 mbps upload on a Premier package.  Multiple speed tests report the same stats, even the one here... https://www.cox.com/residential/internet/speed-101.html
