How do you know the Facebook Like button is not performing up to spec? How about when Google confirms it for you with a glaring “Page Not Found” result. Clicking on the link gives you this result in fact. Some reports are saying this is a random error – but it would have to be significant to get Google to update the index in this manner.

I wonder if there is a security hole that hackers have found or just the challenges of rolling out new code and having it work on hundreds of millions millions of pages in such a short amount of time.
