Do you have more sources on the web for the video? One video on the first domain and the other on a another server? The player will import those videos into the player, when one sever is down with that video on it, the video will be avaible! The reason is that it will use the other resource of the other server. Read more about this method.
This only works when you have imported the two sources of the video. This can look like this:
videoUrl: ['http://mydomain.com/videos/my_video.mp4', 'http://my-backup-domain.com/videos/my_video.mp4']
This also works for the .ogv and the .webm!
