The only thing you gotta do is put “hyves” as a subdomain in front of the domain to be checked.
=> hyves.domain.com
It´s important that hyves is no existing subdomain of that peticular domain, otherwise it won´t work!
You will now get one of three different results for the pagerank of this non-existent subdomain -> PR7, PR4 and PR0.
PR7 means that the domain is perfectly fine
PR4 means that the domain got penalized by google
PR0 means that the domain got banned in Google
Pretty cool.

It’s not working for me. Is it working for others? 5:08 PST 2009-01-20
Well, It worked 4 hours ago. Not working now. I guess Google would rather be clandestine and shrouded in secrecy than simply allowing webmasters to access a useful tool like this.
That’s what you get from hiring too many ex-CIA spooks.
I saw this over at the webmasterworld or somewhere similar and there are a couple dozen comments that this workaround has been closed.
