CrowdStrike released information to fix affected systems last week, but experts said getting them back online would take time as it required manually weeding out the flawed code. Wednesday's statement was in line with a widely held assessment from cybersecurity experts that something in CrowdStrike's quality control process had gone badly wrong. The incident has also raised concerns among experts that many organizations are not well-prepared to implement contingency plans when a single point of failure such as an IT system, or a piece of software within it, goes down.
