No, but it's a harder proposition to have fibre runs to a server which is in the ocean. You can throw a normal server somewhere silly and connect to it wirelessly, this is just the one remarkable exception.
What if you hook up to some of the undersea fiber that's already there? (I still think this is a bad idea)
I don't think that's possible, it would be sheathed in extremely thick steel and not something you can just splice onto.
