I think most of us on here jumped on it and found the issue. All normal users did not receive an update is pending notification so I would guess that this didn't spread too far in the wild.
Going forward, I will wait a few days to see what the internet is saying before updating. What the heck has happened to Apple?
Im still trying to figure out what a normal non-techie person would do in this situation if they updated via OTA. Even your typical Android user would not know what to do let alone iOS users if they lose cell service. I never had issues with my non-techie wife accepting updates until today. Nothing good can come out of this. This is worst then those iCloud leaks. Losing cell service is pretty critical.
