Google Toolbar PageRank Gone

On the heels of a highly isolated StumbleUpon disappearance, my string of internet anomalies continues. The PageRank has gone missing from the google toolbar. As of this morning, for every site I visit, my google toolbar in both IE and FIrefox has lost the little green progress bar. Upon rollover, I get the following message "No PageRank information available."

I checked a few other computers in the office and we're all seeing the same thing. Anybody else out there seeing this?
