I've gotten it once in a while, probably something to do with where the target sites are mirrored.
Aside - One of the best uses for Google is to check spelling.

Yeah, spelling, especially of people and places. The dictionary(online) isn't much help if you can't spell it exactly, unlike a real dictionary where you can guess and then peruse. When Google says "Did you mean..." they are usually right.
Another use is when you have a url that's close, Google will usually get to where you want to go, rather than "The page cannot be displayed".
So if you're lazy, sloppy and dumb like me, Google is your friend.
