Google can update pagerank, but some data of my blog not have PR. What's happen some datacenter not have PR to my blog, but my blog have PR3, PR2 and PR1 now?
as far as difference in pr is concerned its normal coz different datacenters have different bods but as far as this fall in pr is concerned you should look if there is a sudden decrease in backlinks or updating of your site all of a sudden. that could be the reason. also make sure that you dont get into redundancy i mean if you have the same content posted again (by mistake or something) that could have be the reason as well well thats what i think hope you will be benefited gaurav
