A new report (pdf) on MapReduce, the new programming model use by Google to processing and generating large data sets, his now at Google Labs, I found thoses :

We wrote the first version of the MapReduce library in February of 2003, and made significant enhancements to it in August of 2003, including the locality optimization, dynamic load balancing of task execution across worker machines, etc.

The update of the Google index following thoses was in mid-november and was the most talk about update. Coincidence ?
