Why do most data centers show 835 results for the phrase "submitted with article distributor" while 3 data centers report 870 results, and two data centers report a wopping 14,700! This can be demonstarted by using a multi-dc search like this one http://www.seologs.com/data-center-check.html
That would be it. One IP was slightly different than what Matt Cutts siad, butthat's still a good enough explaination for me.
Yeah, I have seen the higher number of pages on a few other servers recently myself but not quite sure if they are now part of the bigdaddy test or if it's some other test. I've actually seen 3-4 different sets of pages indexed for the same sites floating around recently.
