Marsh, the world's largest insurance broker, said that after a global computer system failure caused disruptions in the operations of airlines, banks, and government institutions, dozens of customers are preparing to file claims. Meredith Schnur, the company's head of network business in the US and Canada, said that over 75 clients have sent potential claims notices to its network insurance providers. Although the claims have not yet been formally submitted, these notifications provide some insight into the extent of the impact of the incident. Schnur said that the affected customers are mainly CrowdStrike users, whose software update defects caused great chaos, but some customers may have suffered indirect losses.
