Global tech outage eases after widespread disruption
Services from airlines to healthcare, shipping and finance were coming back online on Friday after a mistake in a security software update sparked hours-long global computer systems outages, another incident highlighting the vulnerability of the world's interconnected technologies.

After the outage was resolved, companies were dealing with backlogs of delayed and canceled flights and medical appointments, missed orders and other issues that could take days to resolve. Businesses also face questions about how to avoid future blackouts triggered by technology meant to safeguard their systems.

A software update by global cybersecurity firm CrowdStrike (CRWD.O), one of the largest operators in the industry, triggered systems problems that grounded flights, forced broadcasters off air and left customers without access to services such as healthcare or banking. Global shipper FedEx (FDX.N), faced major disruptions and some moderators who police content on Meta's Facebook were hit.

CrowdStrike is not a household name but it is an $83 billion company with more than 20,000 subscribers around the world including Amazon.com (AMZN.O) and Microsoft (MSFT.O). CrowdStrike CEO George Kurtz said on social media platform X that a defect was found "in a single content update for Windows hosts" that affected Microsoft customers.

"We're deeply sorry for the impact that we've caused to customers, to travelers, to anyone affected by this, including our company," Kurtz told media.

CrowdStrike has one of the largest shares of the highly competitive cybersecurity market, leading some industry analysts to question whether control over such operationally critical software should remain with just a handful of companies.

The outage also raised concerns that many organizations are not well prepared to implement contingency plans when a single point of failure such as an IT system, or a piece of software within it, goes down. But these outages will happen again, experts say, until more contingencies are built into networks and organizations introduce better back-ups.

Chief of Army Staff (COAS) General Asim Munir has said that the legal process of trial against planners, instigators, abettors and perpetrators involved in the May 9 mayhem has commenced under Pakistan Army Act and Official Secret Act as per existing and established legal procedures derived from the Constitution. The army chief's statement came as he visited Jinnah House and an army installation in Lahore, which were blatantly attacked and vandalised by “politically motivated” rioters, the Inter-Services Public Relations (ISPR) said in a handout. The COAS was also given a briefing on events of May 9 dubbed by the military as ‘Black Day’ — the day when Pakistan Tehreek-e-Insaf (PTI) supporters ransacked and torched military installations across the country following the arrest of their leader Imran Khan in a graft case. Addressing the garrison officers and soldiers at Corps Headquarters, Gen Munir emphasised that any action aimed at widening a gulf between people and the milita...
