Cybersecurity firm CrowdStrike reported that "a significant number" of devices affected by the recent global IT outage on Friday have been restored. In a social media update, the company, responsible for the faulty security update that led to crashes of Microsoft Windows computers worldwide, stated it is still focused on restoring all systems.

Microsoft has estimated that the outage, described as one of the worst in history, affected 8.5 million computers globally. Businesses, banks, hospitals, and airlines were among the hardest hit, with some still working to fully recover their systems. CrowdStrike expressed its understanding of the profound impact and gratitude for the efforts of its customers, partners, and their IT teams. "We apologize for the disruption this has created," the company added.

CrowdStrike also announced the deployment of a new fix aimed at accelerating the recovery of computer systems. However, the firm did not specify how many devices remain impacted. According to aviation tracking platform FlightAware, over 1,400 flights into or out of the US were canceled on Sunday, with Delta and United Airlines being the most affected.

Health services in Britain, Israel, and Germany experienced disruptions on Friday, leading to some canceled services. The massive outage has highlighted the vulnerability of global computer networks, demonstrating how a single glitch can cause widespread chaos. Lina Khan, Chair of the US Federal Trade Commission, commented on social media, "These incidents reveal how concentration can create fragile systems."

Before this incident, CrowdStrike was considered one of the most trusted brands in the cybersecurity industry, boasting 29,000 customers globally, including some of the largest US companies. Notably, China was largely unaffected by the outage, as CrowdStrike is not widely used there, and the country is less reliant on Microsoft.
