I just noticed that on my team’s billing page, in the Bandwidth used per day graph, the rightmost bar (the one grows when refreshing the page) is actually showing yesterday’s date in its tooltip. I can only assume that the entire graph is off by one day as well, as the tooltip for the leftmost bar is showing a date out of range.
Similarly, the same graph claims that it’s showing the data up to tomorrow’s date inclusive, which doesn’t make a lot of sense considering there shouldn’t be any data yet for that date anyway.
I believe this should be investigated, in case it is a sign that billing is not properly calculated.
Note that I’m in the Eastern Time zone, in case it matters.
