Después de varios días sin novedades oficiales de Google acerca de la ultima actualización, el empleado de Google Matt Cutts, responsable del grupo anti-spam, resume en su blog los diferentes pasos de la actualización:

(a quickie post for those SEOs who can’t resist watching data centers)

As Jagger1 and Jagger2 wind down and Jagger3 is visible at 66.102.9.104, I wanted to recap where things stand.

* Jagger1 was visible at most data centers starting around 10/16/05. A second, refreshed version of Jagger1 was visible recently at 66.102.7.104 and was at all data centers by 11/7/05.
* Jagger2 was visible starting at 66.102.9.104 starting around 10/27/05. Jagger2 was visible at all data centers by 11/6/05.
* Jagger3 was visible starting at 66.102.9.104 around 11/4/2005. Jagger3 is not widely visible yet (it might also be at 216.239.51.104), but I expect it migrate to other data centers over time.

Q: Is the update winding down?
A: It’s starting to. Recall that all of Jagger1/2/3 are separate changes. Jagger1 and 2 are done, and you can see what Jagger3 will look like at 66.102.9.104.

Q: Do you still want spam reports if I see things like hidden text, hidden links, etc.?
A: Absolutely. We’re working through the reports that we’ve received, but I’d love to have more. Just to repeat, you can do a spam report at http://www.google.com/contact/spamreport.html with the keyword “jagger3? and we’ll check it out.

Finalmente, después mas de tres semanas de incertidumbre, el nuevo indice de Google ya se ha consolidado con los resultados de Jagger1, jagger2 y Jagger3 en el centro de datos (DC = data center) 66.102.9.104. Ahora, su propagación a todos los demás DC’s durará todavía algún tiempo más.
