Google dump a 2nd level domain
It seems that in the wee small hours (GMT) of April 1st 2005 Google nuked Australia from the face of the planet, or at least the Google datacentres. 1st reports of there being no .com.au sites within Google started to appear at about 4am GMT...
There was no www.google.com.au according to Google let alone any and every business, personal site, informational resource or hobbyist site that lived under the com.au namespace.
Google reps started to repond and acknowledge the problem at about 7:30 GMT and the problem soon got resolved but it is kind of scary that a whole country's official domain name space can get lost.
The engineers work at deleting 2nd level domains from the SERPs.
Google, sometimes 2nd level domains are legit and just because an engineer may not be worldy wise enough to know about the com.au namespace doesn't mean it should be added to a spam list!
It's worse still when it's done on April 1st and it isn't a joke!
