 I'm going to go see my friends that just put on hospice yesterday, and we can't get out. Some of the airline's ground stops have now been lifted. But what happened? Security firm CrowdStrike blames a glitch in a Windows update that was put out overnight. Matthew Frazier is New York City's chief technology officer. It impacted a number of workstations. And what you're seeing across not just New York City, but across the global estate, anyone that's a customer of theirs, you're seeing an impact to anything that received the update during that period.
