 This is a special report from ABC News Global IT Outage. I'm Sherry Preston. Around the world, banks, online retailers, media outlets, and airline flights have all been affected by a worldwide computer outage. This woman is at Reagan National Airport in Washington. When I got here, there was a lot of chaos about an hour ago, and they kind of told me there was a ground stop, and I kind of asked what that meant, and I don't know. I didn't get a lot of clarity, but I am going to have to cancel my flight and actually get on a new flight at a completely different airport.
