Google Data Centers List for SEO

Google Data Centers List for SEO

HERE is a list of about 122 currently active server clusters(?) at 40 Google Data Centers (C-blocks). Since the active servers do not update in any predictable way, it can be helpful for SEO to observe various individual active servers for search engine optimization purposes.

Top generic search position is valuable. To check your position on a particular data center server, click on the server link below, and search normally. Recent Google updates often appear on random centers, sometimes days before they appear in a "generic" Google search.

Read the forums, follow the SEO guidelines, and keep your hat white.
And Good Luck! A matrix presentation has been added, for clarity.

(all tests done in California)
BLUE = Currently Active, but there are frequent changes (click to check if available)
BLACK = They were here and now they are gone (click to check if they returned).

If you want to save a lot of time doing search engine optimization, and if you don't want to check your SERP position above one-at-a-time, then go automatically check your SERP position on almost ALL the data centers listed above, at I see that the old, excellent McDar Google Dance Tool has disappeared.
