VMBU Summary strange behaviour

[#1]

Today is the 1st of a new month for me.
Earlier, when checking VMBU, the summary (Top of page) was showing as all Free usage (graphically and numbers) equal to last month's Total usage, and zero paid for usage.
When using 'View your Usage History', there was no entry for last months usage.
'This week's usage in detail' was correctly showing today's (last night) overnight usage and a small amount of paid for usage.
Latest check, everything is now displaying the new month's usage, and the usage history for last month is now there.
I don't know if anyone else has seen this, and I presume is due to the various different scripts running as the account payment etc. is being processed.

Hiya,
At a guess it's probably caused by the delay inbetween the billing script and the point at which your usage reset, which happens a little bit later.

I see that sort of behaviour too during the roll-over part of the billing day. The numbers eventually come out right when roll-over completes.
Chalk it up as one of the unintended "features" that computer systems are good at.

I Know what you mean.
