What we initially suspected as October 2011 PageRank update was nothing more than a change in the way Google displays PageRank. It was not PageRank update. And it was not a tribute to Steve Jobs. Google periodically tweaks its system and we as third party service providers who use Google data have to make changes accordingly.
We’ve updated our fake PageRank checker in accordance with the changes that Google made, so it’s working now.
Thanks to those who alerted us about this issue.
