I liked the older one better - http://www.google.com/tisp/notfound.html

You might have typed the URL incorrectly, for instance. Or (less likely but certainly plausible) we might have coded the URL incorrectly. Or (far less plausible, but theoretically possible, depending on which ill-defined Grand Unifying Theory of physics one subscribes to), some random fluctuation in the space-time continuum might have produced a shatteringly brief but nonetheless real electromagnetic discombobulation which caused this error page to appear.
