But for several hours, bankers in Hong Kong, doctors in the UK and emergency responders in New Hampshire found themselves locked out of programs critical to keeping their operations afloat.<\/p>\n<div class=\"bzn bzn-sized bzn-intext\">\n<ins data-revive-zoneid=\"79\" data-revive-block=\"1\" data-revive-id=\"36eb7c2bd3daa932a43cc2a8ffbed3a9\"><\/ins> <\/div>\n<p>\u201cThis is unprecedented,\u201d said Alan Woodward, professor of cybersecurity at Surrey University. \u201cThe economic impact is going to be huge.\u201d<\/p>\n<p>The catastrophic failure underscores an increasingly dire threat to global supply chains: The IT systems of some of the world\u2019s biggest and most critical industries have grown heavily dependent on a handful of relatively obscure software vendors, which are now emerging as single points of failure. In recent months hackers have exploited this phenomenon, targeting vendors to bring down entire sectors and governments.<\/p>\n<p>Adding to the disruption, Microsoft experienced a separate and apparently unrelated problem with its Azure cloud service on Thursday that lasted for several hours. On Friday afternoon, the company said in a post on X that all Microsoft 365 apps and services had been restored.<\/p>\n<p>By the New York morning, many systems were coming back online. CrowdStrike\u2019s Chief Executive Officer George Kurtz said in a pre-6 a.m. post on X that the fault had been identified and that the company had deployed a \u201cfix\u201d which required manually rebooting Windows machines. Microsoft said later that it had addressed the underlying cause of its IT issue.<\/p>\n<p>Shares of CrowdStrike dropped 11% at 9:45 a.m. in New York trading, wiping about $7.4 billion off its market value. Shares fell as much as 15% earlier in the day, the biggest intraday decline since February. Microsoft shares were little changed at $437.65.<\/p>\n<p>There are precedents for such outages. In 2017, a series of errors within Amazon.com Inc.\u2019s cloud service affected the operation of tens of thousands of websites. In 2021, issues at content delivery network Fastly took out several media networks including Bloomberg News. Disruptions also incapacitated Amazon\u2019s AWS cloud service.<\/p>\n<div class=\"bzn bzn-sized bzn-intext-2\">\n<ins data-revive-zoneid=\"162\" data-revive-block=\"1\" data-revive-id=\"36eb7c2bd3daa932a43cc2a8ffbed3a9\"><\/ins> <\/div>\n<p>But none of those approached the scale of the CrowdStrike outage, which hit airlines, banks and health-care systems, and whose repercussions are still being felt.<\/p>\n<p>\u201cI don\u2019t think it\u2019s too early to call it: this will be the largest IT outage in history,\u201d Troy Hunt, an Australian security consultant and creator of the hack-checking website Have I Been Pwned, said in a <a href=\"https:\/\/x.com\/troyhunt\/statuses\/1814198760387596407\" target=\"_blank\" rel=\"noopener noreferrer\">post<\/a> on social media platform X.<\/p>\n<p><strong>Airlines<\/strong><\/p>\n<p>Airport hubs from Berlin to Delhi struggled with delays, cancellations and stranded passengers on a day that was particularly busy for travel. FlightAware said more than 21,000 flights were delayed globally.<\/p>\n<p>United Airlines Holdings Inc. and Delta Air Lines Inc. gradually resumed operations on Friday, though the effects of the disruption may continue for several days in light of the busy flight season.<\/p>\n<p>Other US carriers that had temporarily grounded flights included American Airlines Group Inc. and Spirit Airlines Inc., according to the Federal Aviation Administration.<\/p>\n<p><strong>Finance<\/strong><\/p>\n<p>The London Stock Exchange Group has resolved an issue that stopped the bourse from publishing news on its website via RNS, a service that publicly traded companies use to <a href=\"https:\/\/www.bloomberg.com\/news\/articles\/2024-07-19\/lseg-says-technical-issue-is-halting-rns-news-announcements\" target=\"_blank\" rel=\"noopener noreferrer\">distribute<\/a> price sensitive regulatory announcements.<\/p>\n<p>A number of banks were forced to revert to backup systems during the IT failure. Bankers at JPMorgan Chase &amp; Co., Nomura Holdings Inc. and Bank of America Corp. were unable to log on for part of the day on Friday and the trading desk at Haitong Securities Co. was out of action for about three hours.<\/p>\n<p><strong>Health<\/strong><\/p>\n<p>The disruptions also impacted critical infrastructure, including emergency services.<\/p>\n<p>Doctors at the UK\u2019s National Health Service couldn\u2019t access scans, blood tests and patient histories. Memorial Sloan Kettering Cancer Center in New York and Boston-based Mass General Brigham warned that the CrowdStrike issue was affecting patient care. Hospitals in Europe reported having to close clinics and cancel procedures.<\/p>\n<p>New York\u2019s 911 and emergency systems were also impacted. While the state\u2019s chief cyber officer said that fixes were underway, there was no clarity on when services would be fully restored. New Hampshire\u2019s emergency 911 services are functioning again after a failure in which operators could see calls coming in but couldn\u2019t answer them.<\/p>\n<p>Photo: <em>A self check-in kiosk is unavailable at the the Jetstar check-in area of Sydney Airport in Sydney, Australia, on Friday, July 19, 2024.
