Due to MS Cloud Error... Aircraft Grounded and Broadcasts Disrupted

On the 19th, a disruption occurred in the cloud services of the information and communication (IT) company Microsoft (MS), causing flight cancellations at some airports in the United States, Europe, India, and Australia, as well as disruptions in communication, broadcasting, and financial services.

According to foreign media including the Associated Press, major airlines in the United States experienced widespread flight suspensions and check-in delays on the day. Due to the disruption in MS's cloud services, low-cost US airlines Frontier Airlines and Sun Country Airlines faced operational difficulties on their routes. US-based Allegiant Air was also unable to process reservations and check-ins.

In Australia, flights were canceled, and operations of major broadcasters and mobile carriers were disrupted.

In the United Kingdom, the check-in function at Edinburgh Airport in Scotland was paralyzed, and local broadcaster Sky News announced that broadcasting was impossible.

At Berlin Airport in Germany, check-ins were delayed, and airports across the Netherlands' Amsterdam Schiphol Airport and Spain were also affected by the 'cyber disruption,' causing flight operation issues.

MS stated in relation to this, "We are addressing the service issue" and "We are resolving impacts related to the 'MS 365 app,'" according to foreign media reports.

The problematic 'MS 365' is a service that provides various functions including Office, Windows, security software, and cloud computing.

One of the causes of this IT crisis is being linked to the US cybersecurity company CrowdStrike.

According to foreign media such as CNBC, CrowdStrike revealed that the global IT system paralysis occurred while updating the security program 'Falcon Sensor.' However, the possibility of hacking is reported to be low.
