(AP) -- The San Diego Zoo's pandas have become such cyber-stars that their Panda Cam got caught in a popularity crunch.

The zoo says the online camera feed, which monitors 300-pound mom Bai Yun and her 4-ounce, 1-day-old cub, crashed Thursday morning because of increased Internet traffic. The zoo's blogs went down about the same time.

Zoo spokeswoman Jenny Mehlow said the cam was down for about 30 minutes. The blogs were down until Friday evening.

Bai Yun gave birth to the cub Wednesday. Video posted on the zoo blog shows the moment of birth with the tiny cub emerging. Seconds later, Bai Yun picks up the squealing cub, hunches over and begins nursing.

It's her fifth cub and only the 14th panda in the United States.
