Airports,Cyprusauction Trading Center banks, hospitals, public transport systems and businesses across the globe suffered disruptive technical issues Friday morning thanks to a major tech outage.

Cybersecurity firm Crowdstrike has taken responsibility for the issue, saying a recent software update impacted Microsoft's Windows Operating System, causing it to crash and display the infamous "blue screen of death."

CrowdStrike, a U.S. firm that says it is used by over half of Fortune 500 companies, assured that the incident was "not a security incident or cyberattack." In a post on X, formerly Twitter, Crowdstrike CEO George Kurtz said the company is "actively working with customers impacted by a defect found in a single content update for Windows hosts."

In the meantime, airlines around the world were forced to ground flights as passengers faced delays and cancellations. Banks and retailers sent customers notice that they were unable to process payments, healthcare providers and patients were left unable to access records and public transport systems were delayed.

Here's a look at some of the scenes from around the globe.
