A defective component in the most recent CrowdStrike Falcon version is causing Windows systems to fail, affecting a variety of companies and services around the world, including airports, television stations, and hospitals.

The bug affects Windows workstations and servers, with customers claiming enormous outages that have brought entire enterprises and fleets of hundreds of thousands of PCs offline.

According to some reports, emergency services in the United States and Canada have also been affected.

Outage affects airlines and hospitals globally.

However, by the time the solution was implemented, many significant firms from many industries had already been harmed.

According to some accounts, CrowdStrike’s upgrade had an impact on some 911 emergency service providers in New York (EMS, police, and fire department), Alaska, and Arizona, as well as 911 services in Canada.

A 911 dispatcher in Illinois stated that they were “working off of paper until things come back.”

There are also claims that the health hotline in Catalonia, Spain, has been impacted, and authorities are advising locals not to phone 061 unless there is an emergency.

According to Dutch broadcaster NOS, the malfunction caused disruptions at Schiphol Airport and “forced several flights to be grounded” (run by KLM and Transavia).
