I guess less people are using internet at that time at your place.
That ping check isn't very accurate y'know. I'd go by ingame ping rather than that.
Have you never woken up and checked xbox live?Why do you think people stay up so late?
That's because of the increased usageWhen I play It adds 20 ping and thats it.
It didn't. Shot up to back to 200 the next day. :>
