Internet monitoring company Renesys has graphed server uptime for the east coast during the week of Hurricane Sandy. The blog entry has details, but it is notable that they have divided the map into a grid squares of one tenth of a degree. I like the map, but dark/light would help as would weather animation. Also, some indication of server density in a grid cell would be welcome!
[Disclaimer: I do not work for FlightStats, but I have met some of them.] FlightStats has put up a heat map animation of airport disruptions during Hurricane Sandy. This map does have weather, but I think it could use some shading for day/night. Sometimes the flight data looks a bit like the hurricane data, but I think it's a noble effort to summarize complicated information.
To me, both maps show how interconnected modern society is and how data streams can be used to understand the scope of an event.
Here's the recent geonews that haven't made it into an individual story in batch mode.
