Google Multi-Datacenter PageRank(TM) Checker allows you to offer your website visitors a tool to check their PageRank(TM) via multiple Google datacenters. This is very useful to find out if a "Google Dance" / PageRank update is in progress. If no updates are in progress, all ranks will show the same value. If datacenter / PageRank updates are in progress, some datacenters will return different ranks. Online demo available on the product page.
