 Business systems have been crashing. It's a problem that happened during a software upgrade, not, we're told, a cyber attack. But it's affecting flights and banks and governments. Just in the last few minutes, we learned North Carolina DOT's website is down, so you can't go order a duplicate license or do other business. While 911 systems in some cities have been affected by this, 911 is working here in Charlotte-Mecklenburg. That's according to police.
