Hi, At the time of PR update i found that Google has decreased the PR of YouTube from 8 to 3. I also check that in different datacenters at that time i found that YouTube has a PR 3. But now today i checked YouTube PR in different datacenters then i found that in some datacenters YouTube showing PR 8 and in some datacenters YouTube showing PR 3. Why Google did that after the decreasing PR of YouTube it increased again. Anyone noticed that their website PR decreased and then increase. Tell me your suggestions. Thanks
