Private Whois: Out of index?

[cangoou]

Hello! My registrar got a Denial-Of-Service-Attack, anyway while restoring the data they set a domain of mine to "private" status, which means you cannot see the whois-data. Now my domain has lost alle it's PR, and it's not in the index anymore (site: no results).

Is Google blocking domains with a private whois? Or is this just a coincidence and I have to look for other reasons?

Private Whois is not a problem for Google, at least not in itself. If it's combined with other signals of manipulation it can help add up to a negative treatment of some kind. But on its own there are so many legitimate reasons for private whois that Google does not use it as a sole reason to penalize.

Have you checked in your Webmaster Tools for any relevant information about spidering troubles?

Thanks for your reply. I havent got a webmaster-tools-account for this domain yet, but I think I will install one to see whats going on.

Hm, in the Webmaster-Tools there are no errors. Google is just telling me that there are no pages indexed at the moment and that this could take some time and that I should read the webmaster guidelines... But the page already was fully indexed a week ago.

Any ideas to isolate what problem it could be?

"Having lots of sites isn’t automatically bad, and having PPC sites isn’t automatically bad, and having whois privacy turned on isn’t automatically bad, but once you get several of these factors all together, you’re often talking about a very different type of webmaster than the fellow who just has a single site or so." -- Matt Cutts [mattcutts.com]
