Due to Microsoft Azure: Friday morning started with an unexpected turn for the world, shifting from real-world conflicts to cyber issues. Several airlines in the United States reported communication disruptions with the Federal Aviation Administration (FAA) and requested a ground stop, leading to major airlines halting worldwide operations briefly.
Airports worldwide experienced widespread system failures, with Flight Information Display Systems (FIDS) showing the dreaded “Blue Screen of Death.” Operations at both airport and airline systems ground to a halt.
The root cause was identified as a technical issue with software from global cybersecurity firm CrowdStrike. This company provides antivirus solutions for Microsoft Windows devices. In a statement, Microsoft acknowledged, “Earlier today, a CrowdStrike update caused widespread IT system disruptions. We are actively assisting customers with recovery efforts.”
The outage impacted multiple sectors using the Microsoft-CrowdStrike combination, including emergency services, hospitals, and courier services.
In India, airports and airlines communicated via social media about the disruptions. Passengers voiced their frustrations on social media about blank screens, halted check-ins, and inoperative booking systems.

Why Were Airlines and Airports Affected?
The faulty update didn’t just affect individual PCs; it also impacted Microsoft Azure, the cloud storage platform, and the 365 services platform. This explains why only some airports and airlines were affected. Airports operated by the Airports Authority of India were not impacted, but major privately-run airports like Delhi, Hyderabad, Mumbai, and Bengaluru were, with Delhi experiencing the most significant impact.
Airlines heavily reliant on Azure for website hosting, booking engines, revenue management systems, and Departure Control Systems were hit the hardest. However, some airlines not dependent on Azure experienced minimal disruption.
How Did Airlines Respond?
In response to the system failures, airlines resorted to issuing boarding passes manually, a challenging task, especially for passengers needing multiple passes for connecting flights. The Departure Control Systems outages had a domino effect, complicating operations further.
Airlines provide manual operations training as part of their staff refresher courses, but handling a high volume of delayed flights posed a significant challenge. Many flights were canceled or delayed, with airlines offering alternatives or refunds where possible. Airports used whiteboards to update flight statuses and gate information.
What Should Passengers Do?
Passengers are advised to remain patient. These issues are beyond the control of airlines and airports, and all efforts are being made to manage the situation. Travelers should check their flight status with the airline before heading to the airport and stay alert for messages or automated calls from the airline.
The system disruptions continued through the end of Friday and are likely to have residual effects over the weekend as airlines assess the situation. Passengers flying over the weekend should verify their flight status in advance.
Conclusion
On the same day Airbus celebrated the certification of its A321XLR, enabling long flights on narrowbody planes, the world struggled to maintain regular flight operations. This situation underscores the interconnectedness and dependency of modern systems.
Airlines need robust disaster recovery plans to handle such disruptions. Whether this outage will impact airline balance sheets remains to be seen, as past compensations from OEMs for planes and engines have sometimes offset losses.
In the face of adversity, the resilience and patience of both airlines and passengers are tested, highlighting the need for better preparedness in our increasingly connected world.
FAQs About the Airline and Airport Disruptions Due to the Microsoft Azure Outage
1. What exactly happened during the Microsoft Azure outage affecting airlines and airports?
The outage was triggered by a faulty update from CrowdStrike, a cybersecurity firm providing antivirus software to Microsoft. This update led to widespread IT system failures globally, impacting airlines and airport operations that relied on Microsoft Azure for their services.
2. How long did the outage last and what was the extent of the disruption?
The outage began on Friday and had lingering effects over the weekend. It caused significant disruptions, with Flight Information Display Systems (FIDS) showing the “Blue screen of death,” halting check-ins, and grounding flights. The impact varied, with some airports and airlines facing severe disruptions while others were minimally affected.
3. Which airports and airlines were most affected by the outage?
Airports and airlines heavily reliant on Microsoft Azure for their IT infrastructure were the most affected. This included major private airports like those in Delhi, Hyderabad, Mumbai, and Bengaluru. State-run airports in India were not affected, demonstrating the varying impact based on the IT systems used.
4. What measures did airlines take to manage operations during the outage?
Airlines had to issue boarding passes manually and use whiteboards for updating flight information. They trained staff for such manual operations, although managing a large volume of delayed and connecting flights posed a significant challenge. Many flights were canceled or delayed, and airlines provided alternatives or refunds to passengers.
5. What advice is there for passengers during such an IT system outage?
Passengers should stay patient and understand that these issues are beyond the control of the airlines and airports.
