All data centers are down across the world. This is not how a typical PR update happens. Hope it comes back soon.
Either PRapi.net is running an old database of pre-checked ranks or it's taping into a new hash algorithm via it's api, I'm favoring the latter. Google's URI is/was utilizing a Jenkins hash function as seen below, all of which are now returning null. http://toolbarqueries.google.com/se...=783326521420&features=Rank&q=info:google.com http://toolbarqueries.google.com/se...402760803&features=Rank&q=info:www.google.com http://toolbarqueries.google.com/se...032110&features=Rank&q=info:http://google.com http://toolbarqueries.google.com/se...65&features=Rank&q=info:http://www.google.com http://toolbarqueries.google.com/se...781130465875&features=Rank&q=info:google.com/ http://toolbarqueries.google.com/se...04551388&features=Rank&q=info:www.google.com/ http://toolbarqueries.google.com/se...98577&features=Rank&q=info:http://google.com/ http://toolbarqueries.google.com/se...2&features=Rank&q=info:http://www.google.com/ It will be interesting to see if the ranks return in the next 24hrs or so, if not it's more than likely given some app's (like PRapi) can still return PR scores, that google has changed hash authentication access maybe as part of their Panda project. Just wishing they return useful features like cache results as it allowed me to seek info by highlighting it from a large body of text, A real time saver! guess they need to second guess what's beneficial to everyone.

Google has always said not to worry too much about PR but to focus on getting quality backlinks and good content
prapi.net no have database , it only have cached , but cache only 3 hours (prapi fixed by change url parameter to request google). Google toolbar pagerank fixed .
true but sites with pagerank usually are quality backlinks . Without pr we can be linking from spam sites!
Hope this is some sort of bug or error and thing will be back to normal soon. No more Google PR would seriously to people who are doing SEO, link selling, etc.
the same problem here . I have two different software but shows nothing on every site i 've checked. Be patient. Something is going to happen
the past few days have been minor pr adjustments, but nothing fancy. Things like that always happen....
As Google Toolbar is already showing Pagerank so nothing to worry about.Other tools like checkpagerank.us or cekpr.com will also show PR and problem will be fixed by today
I think,Google is aking chnages in its Pagerank algorithm and whenever Pr update happens,third party tools are making mistakes in showing PR
you can check use tools www.mypageranker.com its all have problem my site shown n/a or zero page rank , all of them, even google that mean update is happen
