Airlines, hospitals, banks, and countless other companies and services around the world began to slowly recover on Friday (19) after the severe disruptions caused by a global technological blackout. The interruption, which reached proportions that some experts called “historic,” was an impressive example of the fragile dependence of the global economy on certain software and the cascading effect that can arise when a defect occurs.
The disruption was attributed to CrowdStrike, a cybersecurity company whose software is used by numerous industries worldwide for protection against hackers and external breaches. A software update released this week by CrowdStrike appears to be at the root of the problem, resulting in outages on machines running the Microsoft Windows operating system.
George Kurtz, CEO of CrowdStrike, stated that the cause was identified and isolated and was not a security incident or cyberattack. He mentioned that a fix had been sent out but warned that it could take some time to be implemented. “We deeply regret the impact we caused,” said Kurtz on NBC’s “Today” show.
How the side effects were felt worldwide:
• Flight disruptions: U.S. airlines began to restore service on Friday morning after major disruptions across the country overnight. At least five U.S. airlines – Allegiant Air, American, Delta, Spirit, and United – suspended all flights for a time, according to the Federal Aviation Administration. More than 1,500 flights nationwide were canceled on Friday, according to FlightAware.
• Chaos at airports: The problems were also felt at airports around the world, including in Hong Kong, Sydney, Berlin, and Amsterdam. At Manchester Airport in the UK, there were long lines at the boarding area as many machines at the check-in counters were not working.
• Emergency services: The disruption hampered health systems worldwide, leading hospitals to cancel non-critical surgeries and complicating emergency response systems in the U.S. 911 lines were cut in several states, the U.S. Emergency Alert System said on social media.
• Federal response: President Biden was informed about the CrowdStrike disruption, the White House said. Government officials are “in contact with CrowdStrike and the impacted entities” and “engaged across all agencies to obtain sector-by-sector updates.”
• The unaffected: Some essential services, including major banks and supermarkets, appeared virtually unaffected by the disruptions on Friday morning, at least in the United States. Amazon Web Services and Google Cloud, the other major cloud computing platforms besides Microsoft Azure, stated that, overall, their services were operating normally.
What to know if you are traveling this weekend:
Which airlines were affected?
North American airlines American Airlines, United Airlines, Delta Air Lines, Allegiant Airlines, SunCountry, and Frontier Airlines reported issues on Friday. Since then, American Airlines has said it has “safely restored” operations, while United Airlines is resuming “some flights.”
Delta Air Lines has resumed some flight departures, but additional delays and cancellations are expected on Friday.
Ryanair, Air France, and Turkish Airlines also reported problems, while KLM Royal Dutch Airlines stated that the disruptions are “making it impossible to manage the flight.” AirAsia said its “main reservation and check-in system” was affected by technical issues.
Cirium, an aviation analytics company, shared preliminary data with CNN on Friday about the extent of the disruption. Worldwide, there are about 110,000 regular commercial flights on Friday, according to Cirium. By 6 AM ET, Cirium reported that there were 1,390 canceled flights globally, and that number was growing.
This is a rapidly changing situation, so if you are planning to fly this weekend, it’s best to keep an eye on your chosen airline’s social media channels, apps, and website for updated information. Check your flight status before heading to the airport, if you can.
How long will it take for things to return to normal?
Travel is likely to take some time to get back on track, even after the disruption is resolved. The grounding of flights means that thousands of aircraft are stuck worldwide and may be trapped at the wrong airports.
Crew members have limits on their working hours, so staffing challenges accumulate along with flight delays.
Therefore, patience is required, and be prepared to alter your plans.
