Microsoft Live caches its own broken stuff
I had to use IE today to access the MSDN subscriber downloads site. Since the URL I usually use wasn't working, I just used the IE search bar to find it. I got a laugh out of Live caching the title of the MSDN page being broken. You can probably see the same thing yourselves: http://search.live.com/results.aspx?q=msdn+subscriber+downloads&src=IE-SearchBox
That's bad, it's just....bad.
