I have just checked one my sites and saw that PR is N / A for the index page - www.domain.com but the subpages are keeping their PR's. Could this be a sign of ban or what? Thanks in advance.
I'm noticing a switch to PR N/A on a lot of different pages. I looked at the datacenters and a lot of them are turned off which is why a lot of the pages are going to PR N/A. Google is obviously updating or doing something because a lot of the datacenters are off.
Perhaps they are gradually turning off the evil green bar. I think Google realizes that PageRank has evolved into something of a nuisance.
I would not be surprised in the slightest, but I think that some of the data-centers are currently down. It seems like every update, they are showing PR for fewer and fewer pages, but there are some major domains that are grey right now at the root - that's a little farther than I think Google would go right now.
PR is assigned on a page per page basis so its possible to have N/A on one page and a rank on another for your domain. However the most likely cause to this is that datacenters are down or in the process of updating. The toolbar PR is pretty worthless any way to begin with and can't be trusted as its usually pretty old
Pages on my sites cycle between N/A and an assigned PR value all the time. Nothing out of the ordinary for this to happen.
My site www.sanzrao.com and sanzrao.com had pr 1. But now sanzrao.com shows N/A but www.sanzrao.com is still pr1.
