Depends on what you mean by an "attack." There have been numerous configuration errors by people in the middle such as UUNET, Sprint, etc which affected other ISPs networks for hours or days. I wouldn't call them attacks because an attack implies intent. Stupidity and sloppiness could explain most of them. Could a person with malicious intent do the same thing as the accidential disruptions we've already seen? Yes. Has it happened? I don't know the motivations of the people involved.
