On the placeholder page it explained exactly what was going on. The website exceeded it's data transfer amount for the month and depending on how your web hosting handles it, they might simply charge a fee for the excess or shut down the site altogether until a new month comes around or until extra allowance has been purchased.
I would've contacted Cisco sooner about it but I didn't have his contact details at the time.
Has done the same before so I knew it was nothing to worry about. If it happend half way though the month then it would become an issue.
But I also see theres an issue with the add bar on the left, Its always saying Gathering Data.... Could there be an issue with it and that could be using up the sites data allowance? just wondering.
