My Google rank disappear

[PolyS]

Hello !

I have blog from 4 months and after 3th month I receive page rank 3 from Google. But after Google toolbar has been updated my page rank disappear.
Just from time to time it appears again.
Some suppositions?

Google has many datacenters (at least 40 main ones). Each one keeps an index and a pagerank database. They are never in sync.

You can check in PR check tools. They will give correct information. Google Toolbar is not always correct.

The toolbar PR gets computed 3-4 times a year, so most of the time it is out of date.
