The term overselling means that you are offering bandwidth or disk space in excess of what you have on your overall plan with us. For instance, your plan allows for 100GB of bandwidth usage per month, but you host 100 domains with us, offering each customer up to 10GB of bandwidth per month.
At Page-Zone you would not have to divide 100GB by your 100 customers, giving each 1GB of bandwidth. You could offer much higher, knowing that the average use by all would be within the limit, as is usually the case.
