There were three cancellations at Dublin airport yesterday as computer systems were hit by an outage caused by CrowdStrike’s anti-hack software. A small number of Ryanair and Aer Lingus flights were among 8,880 cancelled worldwide, according to Cirium. More than 42,000 flights were delayed.
Dublin was scheduled to handle 118,000 passengers, of which 58,000 were on departing flights.
A Sunwings flight from Dublin to Antalya was also cancelled. Vueling and Iberia were unable to check in passengers. Twelve US bound flights from Dublin and three from Shannon suffered delays when American, Delta and United each grounded their fleets for a period.

Berlin and Zurich airports were closed for a period. Swiss air traffic control imposed restrictions for a time. Eurowings grounded flights for a period.
