This reminds me of a funny story. I was a tech manager for the Winter Olympics in 2010, allocated to the mountain venues. We had this crazy test rehearsal day where we'd test our systems and processes. Proctors would actually walk around the various venues at the Olympics and just randomly create both big and small problems to see how we'd respond. Suddenly, our network connection to the primary datacenter went down, and we couldn't figure out why. We later learned that a boat had somehow (I don't know how) cut a main underwater cable that connected the mountain areas to the city. It was a stupid day. :)
Are you sure it was a boat? The fibre providing most of the connectivity from Whistler to Vancouver runs along the highway and has been cut by traffic accidents, but I don't think there's anywhere that a boat would kill it...
