For the first time, I saw an error on Google's SERP.
It said: "Error: The server could not complete your request. Try again in 30 seconds."
Here is the screen-shot: http://imgur.com/kqNhU

This error exists since last week http://twitter.com/Zorgloob/status/28030531897
It seems nobody at Google cares about it :-/

TOMHTML: Alternatively, they are well aware of it but its a problem that takes more than a week to fix!
