Facebook Page Admin "like this" points to Insights, is it a bug ?

I'm a page admin on Facebook, till yesterday if I clicked on "like this" link it opened a new pop up and showed the list of people who have liked this page. Today when I clicked on "like this" it took me to Insights page. Is it a bug ?


However within Insights there is a "See likes" link which shows the list of people who are page fans. But this sounds like a bug.
