text:  Quite a lot. Just yesterday, we saw thousands of flight delays around the entire world, cancellations of non-emergency surgeries. There were outages for 911 emergency services. I'm actually in Aspen, Colorado, for a family trip. The local public radio station had some issues broadcasting, but they pulled it off. I'm flying back home to D.C. today and hoping things are a little less chaotic. Well, good luck. Have we seen anything like this before?
