REUTERS: A worldwide tech outage crippled industries from travel to finance yesterday before services started coming back online after hours of disruption, highlighting the risks of a global shift towards digital, interconnected technologies.
A software update by global cybersecurity firm CrowdStrike, opens new tab appeared to have triggered systems problems that grounded flights, opens new tab, forced some broadcasters off air and left customers without access to services such as healthcare 
or banking.
CrowdStrike CEO George Kurtz said on social media platform X that a defect was found “in a single content update for Windows hosts” that affected Microsoft’s, opens new tab customers and that a fix was 
being deployed.

Microsoft said later yesterday that the issue had been fixed.
“We’re deeply sorry for the impact that we’ve caused to customers, to travellers, to anyone affected by this, including our company,” Kurtz told NBC News’ “Today” programme.
“Many of the customers are rebooting the system and it’s coming up and it’ll be operational,” Kurtz said. “It could be some time for some systems that won’t automatically recover.”
But even as companies and institutions began restoring regular services, experts said the cyber outage revealed the risks of an increasingly online world.
“This is a very, very uncomfortable illustration of the fragility of the world’s core Internet infrastructure,” said Ciaran Martin, professor at Oxford University’s Blavatnik School of Government and former head of the UK National Cyber Security Centre. While the core problem appeared simple, which should make it short-lived, its immediate impact was remarkable, 
Martin said.
“I’m struggling to think of an outage at quite this scale.”
Accelerated by the COVID-19 pandemic, governments and businesses alike have become increasingly dependent on a handful of interconnected technology companies over the past two decades, which explains why one software issue rippled far and wide.
