A three-alarm blaze drew 60 firefighters to Apple's Cupertino campus on Tuesday night. Specifically, it was in building Valley Green Six at 20705 Valley Green Drive. San Francisco's ABC 7 television news has some video.
Investigators suggested that an air conditioning unit could have been the culprit. Fortunately, all employees escaped unharmed. No word on how much damage was done to the building, although some reports say the smoke damage was substantial.
We're very glad that no one was hurt, and hope the damage isn't too bad.
Thanks to everyone who sent this in.
