Google Update Bourbon

Webmasterworld has named the latest Google update "Bourbon".

To be honest, though several datacenters are showing different results, I have yet to see them propagate into the regular google.com results.

What does this mean? Hard to guess, usually when changes are in the data centers, but not in the regular results, the changes in the DCs fluctuate, as Google tweaks the results. But in the few SERPs I checked, they've remained the same in the data centers for several days, but haven't started appearing in the regular search results.

However, several posters in webmasterworld are claiming "75% drops" in Google traffic and the like - so it could just be that my "pet" keywords haven't been affected.

Though the general mood seems to be one of panic - I'd counsel patience, even the "Florida" update went through a number of iterations (nearly 3 weeks) before they got it right.
