You may have already noticed, but a good number of media outlets, especially blogs like Gawker and the like, have been hit by Hurricane Sandy.
Even though the article above says "everything appears to be back up," that's not the case. Gawker is still down, at least for me here.
Now, I'm not a rocket scientist, but why does this happen in this day and age? I worked for a phone company over twenty years ago; when events like this happened, there was a switch in Chicago or a switch in California that would happen automatically and allow for service to continue. It would seem to me that if you have a datacenter of some kind on one coast that you'd pony up a few extra bucks to have a mirror somewhere else to help keep your site or your service up and running.
