FRANKFURT, Germany — A global technology outage grounded flights, knocked banks and media outlets offline and disrupted hospitals, small businesses and other services on Friday.
Cybersecurity firm CrowdStrike said that the issue believed to be behind the outage was not a security incident or cyberattack.
"We understand the gravity of the situation and are deeply sorry for the inconvenience and disruption," Crowdstrike CEO George Kurtz said.
In an interview with the TODAY Show, Kurtz explained the outage was caused by a software bug included in an update that went out to Windows machines. He said the issue was identified quickly and a fix was sent out, bringing some computers back online quickly.
"We identified this very quickly and remediated the issue," Kurtz said. "And as systems come back online, as they're being rebooted, they're coming back and they're working."
Despite that, Kurtz said some systems weren't able to accept the automatic update to fix the bug. For those systems, it could be a while before operations are restored.
"Many of the customers are rebooting the system and it's coming up and (being) operational because we fixed it on our end," he said. "Some of the systems that aren't recovering, we're working with them. It could be come time for some systems that just automatically won't recover."

As of 5:45 a.m., American Airlines said it was re-establishing operations. Around 10:30 a.m., the airline announced that it would be issuing travel waivers.
