The good news: It looks like no one got it hurt as it was a very late. A 3-alarm fire broke out at an Apple
R&D IST facility a few hours ago. As of this writing it is still burning as firefighters in Cupertino try to contain it.
More as it comes in… since everyone is safe, we send our prayers out to all of the future iPods, Macs and iPhones that hopefully will get to see the light of day.
UPDATE: Firefighters have put out the blaze. The three-alarm fire burned for over three hours at Apple headquarters. The fire scorched the roof and the second level at one of the six buildings on the company’s northern California campus in Cupertino. There were no injuries, but the building is understood to have suffered "a lot" of smoke damage. Link.
