They don't actually own the oil they're pumping, right? So if their billing was compromised to the point that they don't know what oil needs to be pumped where, they had a legal duty to refrain from pumping it willynilly.
(Oh shit, everything just went down, turn on the generator, go plug that printer and laptop in, and print off all the reports of where we were from the offsite/offline/whatever backup).
What did they do before computers?
Failing to plan is planning to fail and all.
I like the idea of monthly planned downtimes where possible so people don’t run around like a headless chicken when things go down. No different than a fire drill.
If they did, I would expect their employees to be out of practice with such methods since they weren't working that way day-to-day. Unless they're running regular "all computers are down"-drills to keep their employees sharp, downtime was probably inevitable.
