Strange thing, some of the toolbars in my office are showing an update of PR and others are not. I never noticed this behavior in the past. Has anyone else seen this?

I noticed that this morning but figured checking each datacenter was a better option anyway.

It was in the middle of the update and probably the update was being reflected on each ip/machine google has its data.

data transportation delay is quite normal in internet. Maybe that's the reason.

I got the same thing on all our sites. Once the update was over the results were fantastic. All our newly lauched sites got great PR some of the already well linked sites went right to 5, WOW
