Massive tech outage causes worldwide disruptions, fix on the way

Much of the world faced online disarray Friday as a widespread technology outage affected companies and services across industries — grounding flights, knocking banks and hospital systems offline and media outlets off air.

At the heart of the massive disruption is CrowdStrike, a cybersecurity firm that provides software to scores of companies worldwide. The company says the problem occurred when it deployed a faulty update to computers running Microsoft Windows, noting that the issue behind the outage was not a security incident or cyberattack.

CrowdStrike has said a fix is on the way. Still, chaos deepened hours after the problem was first detected.

Zimmer Marketing Senior Web Developer Jason Dittmer says the “Blue Screen of Death” is something all in the industry fear.

 Friday’s disruptions began when a faulty update was pushed out from CrowdStrike for one of its tools, “Falcon.” In a statement about the ongoing situation, the company said the defect was found “in a single content update for Windows hosts” — noting that Mac and Linux systems were not impacted.

But, because scores of companies rely on CrowdStrike for their security needs with Windows as their operating system, the consequences of this kind of technical problem have been far-reaching.

Long lines formed at airports in the U.S., Europe and Asia as airlines lost access to check-in and booking services during peak summer travel — disrupting thousands of flights. Banks in South Africa and New Zealand reported outages impacting payments and online services. Some news stations, particuarly in Australia, were unable to broadcast for hours. And hospitals had problems with their appointment systems, leading to delays and sometimes cancelations for critical care, while officials in some U.S. states warned of 911 problems in their areas.

Elsewhere, people experienced more minor inconveniences, including trouble ordering ahead at Starbucks, causing long lines at some of the coffee chain’s stores. Some billboards in New York City’s famous Times Square also went dark.

Experts stress that Friday’s disruptions underscore the vulnerability of worldwide dependence on software that comes from only a handful of providers.
