I'm seeing changes on the toolbar - but they come and go. So I just did a check on the seo chat tool (http://www.seochat.com/seo-tools/future-pagerank/) on one of my internal pages and 4 x datacentres are showing PR6 the others PR5. went back a few minutes later and all back to 5.
I am also getting PR 0 on the above datacenters + this one 216.239.53.99 On everything else its fine, Hope some temporary technical problem with these, Abhilash.
