The reputation in a site is not updated in some sites
How much time does it take to update the points on all the profiles.
Example: I got 2 upvotes for a question on Askubuntu.com say 15 minutes ago. The points at the top of my askubuntu page shows the update score. Even When I click on my user profile at the top, the page shows the updated scores. When I click on the other stackexchange siblings accounts of mine, everywhere the scores(points) have been updated. But when I check my stackoverflow.com profile page, It shows the previous score i.e. 10 less than what Askubuntu.com and other shows.
I don't know if its a bug or what? Some insight into the process should be good.
