Has Google blocked queries to its PR datacenters? asks a forum in Digital Point Forum. With everyone talking of PR changes, when a user ran a PR query in one of the pr query sites (IwebTool, digpagerank, etc.), most of them return a NR pr for all queries.
The question remains on whether Google has stopped third party PR tools from showing data. Perhaps its a temporary snafus, perhaps its permanent. For more developments on the subject, we will inform ASAP.
