Law firms are investigating potential lawsuits to come out of CloudStrike Holdings Inc.’s global tech outage, but there may be limits on who can recover damages.

San Francisco’s Lieff Cabraser Heimann & Bernstein and Pittsburgh-based Lynch Carpenter are among the plaintiffs’ firms already announcing investigations of the July 19 outage, which impacted thousands of companies worldwide. They are seeking businesses that have been impacted by the shutdowns caused by cybersecurity software firm CrowdStrike.
