Technical Issue With C C Server
I am not sure if the issue is completely resolved but there seems to have been some compromise script running ( Which is creating some delay in display).
Try to open a question which has many comments to see how much time will it takes to display it properly. Seems like your AJAX is taking few moment to process the comment evaluation ( User can easily see "Comment is Hidden.. " Text for Sometimes).
This should be fixed now.
