Some updates to the billing system have caused a problem for units billed customers resulting in their usage for next month starting early, i.e. usage is now being logged for October. Because of the way usage carriers forward, this is unlikey to have much impact on customer in terms of additional charges. However, any customers that think they have lost out, please let us know and we'll make a manual adjustment. The problem has been corrected for next month.
It looks like customers won't get billed top-up and may not get billed units either, so we are working on un-doing this issue so that billing is done normally. Please bear with us.
We are working on this now and should have usage billing back to normal later this morning.
Usage billing has been restored to around 1am Saturday, giving customers 2.5 days of unmetered usage.
