Ahh - wait - I see if you search from the main site, it fails for me now too. http://search.twitter.com works though. Weird. I expect it's due to a some bug/performance failure rather than an intentional censorship. Otherwise search.twitter.com would be censored too.

Both work for me. I have to assume there was just some technical issue (due to unusual volume?) and they have it resolved now.

I hope so.
