Google Page Rank . . . Where art thou?

Most savvy web designers have installed the Google toolbar in their web browsers primarily for the Page Rank feature. This tool reveals the Page Rank assigned to any website or web page by Google. It has long served as a valuable reference for search engine optimization. However, since 5/28/05, Page Rank appears to be disabled. It is not possible to see the Page Rank of any website using the Page Rank toolbar. Why?

There is all sorts of speculation across the Web as to the reasons. However, Google has been absolutely silent on this issue. Rather than add my own speculative blather, let's wait with bated breath for the next move from the ever enigmatic Google.com

Update: As of 5/30/05 Page Rank is back! Ignore everything I said above.
