A deep dive into how -- and why -- Apple keeps its secrets
Apple employees know something big is afoot when the carpenters appear in their office building. New walls are quickly erected. Doors are added and new security protocols put into place. Windows that once were transparent are now frosted. Other rooms have no windows at all. They are called lockdown rooms: No information goes in or out without a reason.
The hubbub is disconcerting for employees. Quite likely you have no idea what is going on, and it's not like you're going to ask. If it hasn't been disclosed to you, then it's literally none of your business. What's more, your badge, which got you into particular areas before the new construction, no longer works in those places. All you can surmise is that a new, highly secretive project is under way, and you are not in the know. End of story.
