She pulled the USB 3.0 drive from the docking station. It felt heavier than 64 gigabytes should. On it was not just code, but a digital skeleton key. The original UCS (Unified Computing System) cluster had been running a version so old that the upgrade path required three intermediate hops. One wrong move, and the entire voice network for a 4,000-person company would flatline.
