I used to, for the last 6 months type in 'Google data centers' and use the tool that was listed #3, it was always there. Today I type in 'Google data centers' and it's gone, in it's place is 'PBS | I, Cringely . November 17, 2005 - Google-Mart', a nine month old article. Keep it up G.
Take a look at this video: http://www.sinfullyfunny.com/Untitled_0004.wmv it's crappy quality, but I kept refreshing the site:my site and every time it was a different result.
Were you expecting a Google Poltergeist to come out of your screen? Pretty amazing how every refresh shows a different value, it's still going on.
415 414 412 420 405 419 412 411 420 420 420 421 420 416 417 400 are the ones I just did. Weird. You should set a redirect from your www.domain.com to your domain.com you have some site: showing up in www. I'd redirect those to make sure google isn't confused.
They are redirected from www to non-www. I did that about 6 months ago. Goes to show what G has indexed.
I do see that now. It's so weird that it changes from search to search. I just refreshed 2 of my domains about 20 times and got the same data each time.
Getting the same... 182 for site.com 88,200 for www.site.com which has been 301'd to the www over a year and a half. The site itself only has about 1000 pages, but I hadn't seen a fluxuation between www and non www in at least 11 months. beats google.
I checked it on 5 of my sites and none of them is showing such patterns. .. may be some different datacenter.
