I recently found this. Google in the past have run a programming contest... Nothing special I know but guess what... the page informing people about it is still online even though the contest ended a few years ago!
http://www.google.com/programming-contest/
Look at the bottom. It says:
"The winning entry will be announced on the Google.com site by Google Inc. on May 31, 2002. Following the announcement, individual winners will be notified by e-mail. Winners have 14 days from notification to claim the prize. Prize may be claimed by return e-mail. Unclaimed prizes will not be awarded."
So it ended on May 31 2002. Looks like google has got a lot of old files on their server. But at least they updated it to add a winners link to go to

Dont you think its about time they took this offline, lol.
