Delta Air Lines sued CrowdStrike on Friday, claiming the cybersecurity company had cut corners and caused a worldwide technology outage that led to thousands of canceled flight in July.

The Atlanta-based airline is asking for compensation and punitive damages from the outage, which started with a faulty update sent to several million Microsoft computers. Delta said the outage crippled its operations for several days, costing more than $500 million in lost revenue and extra expenses.

CrowdStrike did not immediately comment, but a lawyer representing the company pointed out this summer that other airlines had recovered from the outage much more quickly, and said that Delta was being misleading about its response.
