After multiple planes were grounded and canceled due to a cloud services outage in the Central US, Microsoft said that the issue had been rectified. Allegiant, SunCountry, and Frontier Airlines all experienced operational disruptions. Frontier announced that the ground stop has been removed and that it was in the process of starting regular operations again.
Prior to now, Frontier claimed that a "major Microsoft technical outage" momentarily disrupted business operations. SunCountry said that its check-in and booking systems were impacted by a third-party vendor. "The Allegiant website is currently unavailable due to the Microsoft Azure issue," Allegiant said in a statement to CNN.
