Mr. G changed his mind

I think Google changed his mind because last October 10, 2008 Mr. G gave my Design By Pieces a Page Rank of 2.

But today, I was shocked to see that my Design By Pieces blog is back to N/A.

According to http://www.prchecker.info/, the N/A pagerank (grey pagerank bar) might be due to one of the following reasons:

(1) the web page is new, and it is not indexed by Google yet,
(2) the web page is indexed by Google, but it is not ranked yet,
(3) the web page was indexed by Google long ago, but it is recognised as a supplemental (Supplemental Results) page,
(4) the web page or the whole website is banned by Google.

So, I'm not sure if this is just a glitch or is my blog banned by Google?
