I was checking a Site's pagerank in www.digpagerank.com and its showing OFF for the maximum number of DCs. Can you guys check and report here? I guess its just me as I am using a terribly slow internet here. Or its due to the ongoing PR update?
Use Google Toolbar or this great extension for Firefox to check your PR: http://www.quirk.biz/searchstatus/
Probably digpagerank.com yet again got banned from quering the data centers to much in one day, this is common with SEO tool websites that don't know how to effectively use IP revolving backend software.
The same happens with pagerank.net I used it to check my site's pagerank today and for the first seconds I was shocked when it displayed 0 instead of 4. But then I checked with some other big sites and it was also showing 0 for all of them, although they have normally a pagerank of 5 or higher. So I avoided the heart attack and I realized that it is a problem with pagerank.net Then I installed the pagerank check extension for Firefox and checked... fortunately it still works fine and it displays the correct pagerank for my sites.
