The impact of the Microsoft-CrowdStrike IT disruption on airlines across the globe
Global Impact of the Azure Outage
Microsoft-CrowdStrike: Friday began with unexpected chaos worldwide. A major cyber incident affected airlines and airports, causing significant disruptions. The United States witnessed airlines reporting communication issues with the Federal Aviation Administration (FAA), leading to a temporary ground stop and the suspension of major airline operations globally.
The Blue Screen of Death Hits Airports
Airports worldwide experienced a “Blue screen of death” on their Flight Information Display Systems (FIDS), causing check-in systems to halt. This issue stemmed from a technical glitch identified by CrowdStrike, a global cybersecurity firm providing antivirus software to Microsoft for its Windows devices.
CrowdStrike’s Role in the Outage
CrowdStrike released a statement confirming that a recent update caused IT system failures globally.”Earlier today, a CrowdStrike update was responsible for bringing down a number of IT systems globally,” Microsoft said in response to criticism of the issue.

Widespread Effects Across Various Sectors
The outage’s impact extended beyond airports and airlines, affecting emergency services, hospitals, and parcel delivery systems reliant on the Microsoft and CrowdStrike combination. Airports and airlines in India, among others, took to social media to inform passengers about the ongoing issues. Passengers expressed frustration as screens went blue, check-ins stopped, and booking engines failed.
Why Were Airlines and Airports Impacted?
The faulty update affected not only PCs but also the Microsoft Azure platform, including its cloud storage and 365 services. This explains why some airports were affected while others were not. State-run airports in India remained unaffected, while privately-run airports in Delhi, Hyderabad, Mumbai, and Bengaluru experienced significant disruptions.
Airlines’ Response to the Crisis

Because of the system malfunctions, airlines had to start issuing boarding passes by hand. This posed a greater challenge for connecting passengers needing multiple boarding passes. Departure Control Systems, hosted on Azure, were heavily impacted, causing a domino effect on flight operations.
Airlines, trained for manual operations, faced the daunting task of managing a large volume of delayed flights. They canceled numerous flights and delayed many others, offering alternatives or refunds to passengers. Whiteboards were used by airports to display gate information and flight status updates.
What Should Passengers Do?
Passengers can only exhibit patience during such crises. These issues are beyond the control of airlines and airports, which are striving to manage operations under uncertain circumstances. By the end of Friday, systems were still not fully operational, and residual impacts were expected to continue over the weekend.
Passengers flying over the weekend should check their flight status with the airline before heading to the airport and remain alert for messages or automated calls from the airline. The Friday cancellations could cause a cascading effect on subsequent days, potentially extending the disruption.
A Comprehensive Disaster Recovery Plan Is Necessary
The outage highlights the need for airlines to develop a serious disaster recovery plan. The incident raises questions about global connectivity and dependency, as the world struggled to manage a single flight on a day when Airbus received certification for its A321XLR, enabling long flights on narrow-body planes.
Airlines must consider whether such outages will impact their balance sheets and how compensations from such incidents compare to past compensations for planes and engines.

FAQs About the Microsoft Azure Outage Impacting Airlines and Airports
1. What caused the Microsoft Azure outage that impacted airlines and airports?
The outage was caused by a technical issue in an update released by CrowdStrike, a global cybersecurity firm. This update affected IT systems worldwide, including those running on Microsoft Azure, leading to significant disruptions in airline and airport operations.
2. How did the outage affect airport operations?
The outage caused Flight Information Display Systems (FIDS) at airports to show the “Blue screen of death,” halting check-in systems and other critical airport functions. This led to delays, cancellations, and significant inconvenience for passengers as airlines struggled to manage operations manually.
3. Were all airports and airlines affected by the outage?
Not all airports and airlines were affected. The impact was primarily on those heavily reliant on Microsoft Azure for various services, such as hosting websites, booking engines, and Departure Control Systems. State-run airports in India, for instance, were not impacted, while major private airports experienced significant disruptions.
4. How did airlines respond to the system failures caused by the outage?
Airlines issued boarding passes manually, a challenging process, especially for connecting passengers. They also relied on whiteboards to update flight status and gate information. Many flights were canceled or delayed, with airlines offering alternatives or refunds to affected passengers.
5. What should passengers do in the event of such an outage?
Passengers should remain patient and understand that such issues are beyond the control of airlines and airports. They should check their flight status with the airline before traveling to the airport and stay alert for messages or automated calls from the airline regarding any updates or changes to their flight schedule.
