Just made a long thread myself on this issue and I have confirmed the issue to be two things:
1) I was finally told yesterday that the node I am on is at 100% usage in non peak hours which is causing a massive slowdown.
2) Because they are at max usage, they are throttling peoples internet to compensate. People getting caught in this net are going to be gamers/streamers.
To expand: I was told they would be adding more equipment or something to handle the overload and that it would be fixed within a week. I will report back if this fixes the issue that I have had everyday for two months.
I've talked with lead network engineers at both amazon and cox for 4 months. It sounds like the issue you're having is something different. I am specifically talking about packet loss to AWS hosted games like fortnite. This has nothing to do with overloaded nodes and throttling - this has to do with packet reordering. Just read my post man.
