it is just now around 21:00 UTC, but the active player graph for the last 24 hours ends at 02:00. are you psychically projecting player activity 5 hours ahead, or are you 19 hours behind in reporting?

Oh, I just noticed the past 7 days ends in the wee hours of 10/05...

You sure you're reading it right? It's 22:07 right now by my count, and the graph shows me right up to 22:00. The gray lines are 30 minute intervals and the red lines are 2 hour intervals.

It has been the same graph for a few days. I see the 24 hour one ending at 01:45, with the exact graph as yesterday. The week graph looks like it ended around that time on the 5th. (if the calendar date is placed at midday, and red lines are 00:00).

It's updating on my end. Maybe your browser is caching the image for some reason? (Or maybe it has been fixed between now and when you posted.)
