I found a few domains that I would like to register, but the registrars say that they are taken. When I check whois, there are no records for any of the domains that I am interested in. Perhaps they are in the process of being dropped? How would I check out my theory? Does anyone else have an explanation for this behavior? I'd tried Googling this. Most of the hits ask the same question, usually in forums, but none of the answers that I found are useful - they say things like clear your cache, try again later etc.
