Have you ever worked a job that requires high degree of physical world logistics? In times where the primary coordination mechanism is down, any action becomes much slower to implement and often at a direct cost to implementing other actions.

With regard to this case, I don't know any specifics, but I can imagine tools require digital calibration, inventories not tracked outside digital systems, certain meds behind digital access control, and emergency response striained to the point where complicated non emergency procedures would be more risk than benefit.
