The Daily Kos servers live in New York City. Any major outages in that city could cause Daily Kos to go down. Our data center has contingencies in place to ride out any such disaster (generators and whatnot). The address of our data center is outside the mandatory evacuation zone, but hurricanes can change paths, and if the site goes down in the next several days you'll know why. We have our own Plan B's, but let's hope it never gets to that.
More important than any of that, let's hope that everyone in the path of the hurricane stays safe and dry. Frankenstorms are terrifying.
