 The U.S.-based cybersecurity company CrowdStrike is at the center of Friday's global technology meltdown. They say it's linked to a faulty systems update for Microsoft computers, and it was not a hack. Many sectors like banking, healthcare, government agencies, and air travel were impacted. Delta, American, and United all had delays and cancellations. On last check, there are still a couple of flights out of Tulsa canceled this morning, but most are back on track.
