Thanks to the effort of one person spamming this whois tool from multiple IPs many hundreds of times a minute day after day, 
I'm forced to take it down for everyone. I'm sorry that I have no other method to stop this abusive person.

Please go to a registrar and do a whois there. I recommend <a href=http://who.godaddy.com/whoischeck.aspx>GoDaddy's
