Zen's ADSL Broadband Usage Monitor

Did anyone else have a massive jump is their supposed bandwidth usage yesterday? According to my usage data on the customer portal, I downloaded approx 16Gb of data yesterday - which I didn't

I called support this morning and the techie said they had a few other calls along a similar vein but nothing was obvious from their end. They are looking into it though.
