They do that. It's so much better to use another website's stats database. The Stanford ones take so long to update because of the number of users that the actual amount of time they are completely open for viewing is actually very little. That's why they recommend you use another site (like EOC, or my personal favourite, Kakao).
They perform stats updates every three hours, and if you check the site during one of those periods, it won't let you view them. But yeah, EOC's stats are much better.
