View My Broadband Usage

[#1]

Just looking at the 'View My Broadband Usage' page on plus net site. It claims that today we have already used 3.89GB and 2.24GB of that was 'Peak usage'.
It is not even 4pm yet so how can we have used any bandwidth during peak time?

If you are on one of the newer products (BBYW or later) peak time starts at 8.00am

You know you are - Plusnet know you are - but nobody told the automatic systems
