 This is a Bloomberg Money Minute. Flights across the U.S. are being grounded this morning due to a communications issue. The FAA says airlines like Delta, United and American all grounded flights, with only Americans saying now that they're slowly starting to come back online. The disruptions come as the cybersecurity firm CrowdStrike is reporting a major outage affecting scores of businesses. They say the issue is with its latest Microsoft update, and it's not linked in any way to a cybersecurity attack.
