It seems like there are several threads around the SEO forum space that have discussion on a recent PageRank update. Yes, even more recent then the June PageRank update.

There is a WebmasterWorld thread, a few DigitalPoint Forum threads and a few Google Webmaster Help threads. I will only link to two, but there are plenty out there.

In the Google Webmaster Help, Googler, JohnMu, replied to one webmaster saying that he/she should not worry about the last PageRank change because it was likely a “technical quirk.”

The way John said it, made it sound like the error was on Google’s side. Here is what John said:

So I am wondering if the recent PageRank update noticed by a small percentage of webmasters, was a technical bug on Google’s front?
