Other airlines recovered more quickly than Atlanta-based Delta, which said the incident reduced revenue by $380 million and brought $170 million in costs.
Days after the outage, Delta hired David Boies of law firm Boies Schiller Flexner to seek damages from CrowdStrike and Microsoft .
Delta had disabled automatic updates from CrowdStrike but this one reached its computers anyway, the airline said in the suit.
Microsoft discussed various potential enhancements with CrowdStrike and other endpoint security software sellers at a summit in September.
