I'm keeping track of the number of Wikipedia pages in Google's index across all datacenters. The numbers vary widely across the datacenters at any given time so I record the highest instance. From March 21-23 I wasn't recording the datacenter.

3/21: 2710000
3/21: 4170000
3/22: 4550000
3/22: 5170000

3/23: 5440000
3/23: 6490000 
3/23: 7340000 
3/24: 7350000
3/26: 7470000 (64.233.183.99)

4/11: 10100000 (64.233.183.99)
4/15: 11300000 most datacenters
4/17: 11800000 half of all datacenters
4/17: 11900000

I use AutoIt 3, and the following very basic code (it pastes the results to your clipboard):

#include <Misc.au3>
#include <Date.au3>
#include <file.au3>
#Include <string.au3>
#Include <Array.au3>
Global $results

$DCs = StringSplit('64.233.161.99,64.233.161.104,64.233.161.105,64.233.161.147,64.233.167.99,64.233.167.104,64.233.167.147,64.233.171.99,64.233.171.104,64.233.171.105,64.233.171.147,64.233.179.99,64.233.179.99,64.233.183.99,64.233.183.104,64.233.185.99,64.233.185.104,64.233.187.99,64.233.187.104,64.233.189.104,66.102.7.104,66.102.7.105,66.102.7.147,66.102.9.104,66.102.11.104,216.239.37.104,216.239.37.105,216.239.37.147,216.239.39.104,216.239.53.104,216.239.57.98,216.239.57.104,216.239.57.105,216.239.57.147,216.239.59.104,216.239.59.105,216.239.63.104',',')

For $loop = 1 to $DCs[0]
	Global $pagesingoogle = _ScreenScrape ('http://' & $DCs[$loop] & '/search?hl=en&q=site%3Awikipedia.org&btnG=Google+Search', 't <b>', '</b> f')
	$results = $results & @CRLF & $DCs[$loop] & ' : ' & $pagesingoogle

ClipPut($results)

Incidentally, you will also need my custom _ScreenScrape function for this to work properly.
