Businesses worldwide on Friday are reporting IT outages, including Windows “blue screen of death” errors on their computers, in what has already become one of the most widespread IT disruptions in recent years. The outage has affected companies across various sectors, from banks, food chains and brokerage houses, to news organizations, railway networks and airlines.
In the U.K., the London Stock Exchange, Edinburgh airport, and Ryanair reported facing disruptions in their services, while Indian airlines IndiGo, Akasa, and SpiceJet reported that their check-in systems at some airports weren’t functional anymore, warning passengers that their flights might be delayed as a result.
The Hong Kong airport has seen its check-in systems go down, and the South China Morning Post is reporting that the outage has left “the international airport in chaos.” The Delhi airport said a global outage had knocked down some of its services.
UK news broadcaster Sky News faced trouble broadcasting live this morning due to the outage, the firm’s executive chairman David Rhodes tweeted. The New Zealand Herald reported that banking services in the country were affected by the issue, too.
Many customers have reported being unable to restart their computers due to the issue. The outage comes shortly after Microsoft confirmed service problems with its Microsoft 365 apps late on Thursday, which affected several airlines including Delta and United. Microsoft’s services status page says the issues are being resolved.
Notably, the outages don’t seem to be the result of a cyber attack. Several businesses and security experts have pointed fingers at the security firm CrowdStrike, and Australian energy company AGL outright blamed an update from the firm. The firm’s software is used widely across enterprises for managing security on Windows devices and servers.
A post on Crowdstrike’s support forums acknowledged the issue, saying the company had received reports of crashes related to a content update.
The security firm didn’t immediately respond to a request for comment. Microsoft also didn’t respond to a request for comment.
A moderator of the CrowdStrike subreddit said the company was aware of “widespread reports” of blue screen errors on Windows devices across multiple versions of its software. The firm was investigating the cause, the message read.
Crowdstrike’s shares were down more than 14% in premarket trading on Friday.
