No, but their release process should catch major bugs such as this. After internal QA, you release to small internal dev team, then to select members of other depts willing to dog-food it, then limited external partners then GA? Or something like that so that you have multiple opportunities to catch weird software/hardware interactions before bringing down business critical systems for major and small companies around the planet?

What about AV definition update for 0day swimming in the tubes right now?

Sure, those have happened before, but nothing with an impact like last weekend. That's inexcusable. At least definitions can update themselves out of trouble.

What do you refer to "those have happened before"?

Isn't that what happened? Not a software update, not an AV-definition update but more so an AV-definition "data" update. At least that's how I interpret "Rapid Response Content"
