A significant tech outage on Friday caused airlines to cancel flights and disrupted banking, telecom, and media services worldwide, creating widespread chaos and delays.
On Friday, a worldwide tech outage was causing havoc in several businesses, with airlines canceling flights, some broadcasters going dark, and banking and healthcare among the many sectors impacted, as reported by Reuters.
Flight Cancellations Hit Multiple Airlines
United, Allegiant, American Airlines, and Delta Air Lines all grounded flights due to communication issues. Microsoft announced it had repaired the cloud services outage that had affected multiple low-cost carriers, and the order followed shortly after. It was unclear at the time whether the two issues were connected.
Computer systems around the world, including United's, are experiencing disruptions due to an outage of third-party software. United said in a statement that due to ongoing system restoration efforts, all planes are being held at their respective departure airports. "Flights already airborne are continuing to their destinations."
Telecoms and Media Industries Affected Globally
A problem at the worldwide cybersecurity firm CrowdStrike seems to have been the cause of the disruptions experienced by media, banking, and telecommunications businesses in Australia, according to the country's government.
The "Blue Screen of Death"—a crash in Microsoft Windows—is being caused by CrowdStrike's "Falcon Sensor" software, according to an alert emailed to clients and examined by Reuters.
At 0530 GMT on Friday, the alert was delivered along with a manual remedy to fix the problem.
Emails and phone calls seeking comment from a CrowdStrike representative went unanswered. The company's stock dropped 20% in Friday's pre-market trade.
Yahoo Finance shares that Airports in cities all around the globe, including Tokyo, Amsterdam, Berlin, and a number of Spanish airports, reported system failures and delays, affecting the travel business among others.
Banks and Financial Institutions Face Service Delays
While LSEG Group's Workspace data and news platform was down, clients of banks and other financial institutions in South Africa, India, and Australia were alerted to potential service delays.
The cloud provider AWS, which is owned by Amazon, issued a statement stating that it was "investigating reports of connectivity issues to Windows EC2 instances and Workspaces within AWS."
At this time, it is unclear if all of the reported disruptions were caused by CrowdStrike or if other factors were involved.
