As Throwaway stated all fabs are offline. The office portions are online but moving data in and out of the fab is pure sneaker net.

You realize how much of a complete joke airport security is once you have gone through the security gauntlet to get into a fab.

Getting a laptop into the complex is a difficult. USB drives, cell phones, etc. are carefully controlled. Making a direct connection to a tool in the fab with anything is a major PITA.
