Request for information: ISPs and P2P throttling

- Comcast Xfinity
- USA
- Early morning, I'll get the 90000 error and my internet connection will go out, around 5am PST, but now I'm having latency issues that are affecting me in-game
- They didn't have an answer, as my modem doesn't show anything out of the ordinary, and my connection will come back in a few minutes, but nothing I do makes it any faster like resetting the modem, router, and PC

EDIT: Just went out while I was playing, at 1AM PST, right after I left a dungeon, waaaay too close.
