Massive technology outage has disrupted businesses and institutions in multiple countries, throwing airports, airlines, rail companies, government services, banks, stock exchanges, supermarkets, telecoms, health systems and media outlets into chaos.
The disruption was caused by an update to a product offered by cybersecurity firm CrowdStrike, which had caused machines running the Microsoft Windows operating system said, “CrowdStrike seems to have had some sort of mandatory update to its software that went horribly wrong.”
The company had reported that the issue was related to its Falcon sensor product, engineers identifying a “content deployment problem”, said Hull.
“Essentially it happens as you’re sitting in front of your terminal. If your terminal is a Microsoft Windows terminal, it suddenly goes to a blank blue screen. It’s called the ‘blue screen of death’ error. You are locked out of your operating system,” Hull said.
CrowdStrike CEO George Kurtz said on Friday that the company was “actively working” with customers who had been impacted by “a defect found in a single content update for Windows hosts”.
“This is not a security incident or cyber attack,” he said, posting on X.
At the time of reporting, some of the malfunctioning business, companies and computer app systems were beginning to return to normal service, including Sky News in the United Kingdom, which was down for an hour in the morning.
The outages rippled far and wide, with transport systems around the world among the hardest hit.
