By way of EndGadget, proof that smoking can kill the internet.

…which means the whole thing got taken offline last night when a homeless man threw a cigarette onto a mattress under Boston’s Longfellow Bridge, starting a blaze that eventually melted the fiber-optic link between Boston and New York.

This kind of thing is much more common than we imagine, a quick search brings up lots of incidents, and they are happening all the time, the first one I heard of was in 1989.
