A widespread technology outage grounded flights, knocked banks offline and media outlets off air on Friday in a massive disruption that affected companies and services around the world and highlighted dependence on software from a handful of providers.

What to know about the global tech outage:
- Cybersecurity firm CrowdStrike said the problem occurred when it deployed a faulty update to computers running Microsoft Windows.
- The company said a fix was on the way — but hours after the problem was first detected, the disarray escalated.
A cancelled emergency heart surgery leaves a family scared and worried
Alison Baulos, the executive director of the Center for the Economics of Human Development at the University of Chicago, said her 73-year-old father’s emergency open heart surgery was cancelled Friday morning due to the global tech outage, leaving her family scared and worried.
“It’s an emergency surgery so if anything happens, it would be as a result of not having the surgery this morning,” Baulos told The Associated Press.
Her father was waiting at Baptist Hospital in Paducah, Kentucky to find out what will happen next, she said.
Her father was expecting surgery after he received a call from his doctor on Wednesday saying he had eight blockages and an aneurysm. But the family was told the operation had to be postponed due to the outage.

Capital Economics says outage likely to have little impact on world economy
The global computer outage likely will have little impact on the world economy, according to forecasting firm Capital Economics, particularly because it hasn’t disrupted financial markets.
“While things are still very uncertain, we do not anticipate a major macroeconomic or financial market impact at this stage,” Jennifer McKeown, chief global economist at Capital Economics, said in a written comment. “It is encouraging from an economic standpoint that there has been little financial disturbance so far.”
The firm estimated in late 2022 that even a cyberattack that lasted several days would only shave global economic growth by about 0.2%.
“Given that this is not a cyberattack and has not affected all software by any stretch, the implications should be significantly smaller,” McKeown said.
Cybersecurity analyst calls outage historic mistake by CrowdStrike
Richard Stiennon, a cybersecurity industry analyst, said that this was a historic mistake by CrowdStrike.
“This is easily the worst faux pas, technical faux pas or glitch of any security software provider ever,” said Stiennon, who has tracked the cybersecurity industry for 24 years.
He said while the problem is an easy technical fix, it’s impact could be long lasting.
“It’s really, really difficult to touch millions of machines. And people are on vacation right now, so, you know, the CEO will be coming back from his trip to the Bahamas in a couple of weeks and he won’t be able to use his computers.”

What is Crowdstrike?

CrowdStrike listed on the Nasdaq exchange five years ago. It reported last month that its revenue rose 33% in the last quarter from the previous quarter and that logged a net profit of $42.8 million, up from $491,000 in the first quarter of this year.
The company has a partnership with Amazon Web Services and its Falcon for Defender is designed to supplement Microsoft Defender to prevent attacks.
The firm said Friday’s global disruptions occurred when it deployed a faulty update to computers running Microsoft Windows. The issue was not a security incident or cyberattack, and a fix was on the way, it said.
