Some low-cost airlines in South Korea had fully restored their check-in and booking systems 12 hours after disruptions caused by a global technical outage, which also affected the IT and financial sectors around the globe, the state-run airport operator said Saturday. Incheon International Airport Corp. said three budget airlines -- Jeju Air Co., Eastar Jet Co. and Air Premia Inc. -- had recovered their ticketing and booking systems as of 3:30 a.m. A total of 75 flights were delayed due to the disruptions, according to the airport operator. The tech outage was caused by a glitch in cybersecurity firm Crowdstrike's software, which caused Microsoft's Windows operating system to crash. The three airlines use computer systems based on Microsoft's cloud service. Online game companies here were also affected by the technical outage. The management of Black Desert of South Korean game developer Pearl Abyss posted a notice on its website Friday and said it experienced "server instability" due to "sudden failur e" in its equipment. Other game makers, like Gravity Co., the developer of online role-paying game Ragnarok, said they also suffered disruptions. Source: Yonhap News Agency
