The very notion seems insane to me in the IT age where your business is heavily dependent on the IT being up all the time no excuses accepted.

Given that beancounters can't put a price on downtimes until they actually happen or the productivity increases from implementing good IT, this will continue to happen. This is another reason why corporate cybersecurity is just a box ticking exercise giving the illusion everything is going well.

I have to imagine that this incident is a wake up call for a bunch of industries.

This incident has a convenient scapegoat, everyone will crucify Crowdstrike switch the EDR vendor and continue coasting in neutral. Hell Crowdstrike isn't even on the cheap side so the beancounters will be happy if the new vendor is cheaper.

I'm not a IT person but even so I know full well to test before deployment. Heck I won't update the kernel on my PC before I have confirmed that I have a recent Timeshift to draw from if need be.

You imply you're running a Linux distro so you're already a cut above the regular MBAs who have the business awareness of dementia patients.
