What happened?
On Thursday, Microsoft announced that a cloud service outage in the Central U.S. region had led to significant disruptions, including multiple flight cancellations and delays. Low-cost carriers such as Frontier Airlines, Allegiant, and Sun Country were notably affected.
Frontier labelled the incident as a “major Microsoft technical outage,” while Sun Country attributed the problem to a third-party vendor impacting its systems. Allegiant reported that its website was inaccessible due to issues with Microsoft Azure.
FlightAware data revealed that Frontier cancelled 147 flights and delayed another 212. Allegiant and Sun Country faced delays on 45% and 23% of their flights, respectively.
Microsoft stated that the outage began around 6 PM ET on Thursday and affected some customers using various Azure services. The company is also investigating related issues impacting several Microsoft 365 applications and services. The outage may be connected to an update from the cybersecurity firm Crowdstrike, which is causing Windows PCs to display the Blue Screen of Death and preventing them from rebooting.
This disruption has impacted multiple industries, including transportation, banking, and media.

Why it’s important
The Microsoft cloud services outage has caused major disruptions across multiple sectors. Frontier Airlines faced significant service issues, including problems with booking, check-in, and boarding, leading to numerous flight cancellations. Additionally, companies such as Amazon, Cox, and Sky News experienced their own disruptions.
The timing of this outage is particularly problematic, as it coincides with the start of summer holidays in the UK and other European countries, marking one of the busiest travel periods of the year. This incident follows closely after the CHAPS global payment system outage, which had already stalled billions of dollars in transactions.
The impact extends beyond airlines to transportation, with Thameslink trains in the UK reporting widespread IT issues. These problems could lead to cancellations, particularly on the Thameslink and Great Northern routes.
The stability and reliability of cloud services are crucial for various industries in today’s Internet of Everything era. As such, this outage could significantly harm Microsoft’s reputation.
