The Internet Is an Error:
So, something is hosed at the moment. It's likely that the application has run up against its host's CPU quota, or that Google has cut this site off from using their search API because it's made too many hits (they allow about 5000 per day). It's also possible that there's a bug in the code somewhere, and you simply managed to send execution through it -- in which case, thanks a lot. The internet was a sonnet and then you broke it.

Odds are, though, if you check back tomorrow, the site will be running again just fine.
