Since early 90's I've seen it done twice, and I'd hardly call them
extended outages, most would likely have seen brief, but hardly long,
partial outages. 

I've seen however far more regional outages due to BGP f-ups, and no
amount of multiple DNS anycasts are gunna help there since they couldnt
do squat at all anyway :)
