If you check whois from one source there's a danger it won't update, I doubt many people check whois at nominet, it's just not in your face enough, perhaps they do, unfortunately for netbenefit I've been checking available domains using their interface since 1998, they're who I bought my first domain with.
It doesn't matter where in the world whois is updated, it's still realtime and it's good to get a varety of readings especially when the crap site 123-reg fails to follow up on an immediate request and fails to register the domain so checking various sources to ensure you get a domain is vital.
It took an hour but where 123-reg failed, Weycrest succeeded, I used Weycrest because I remembered on this forum thay take paypal so I used namedrive monies that were paid into that account today. I'm not that cryptic, I just keep getting let down by supposed professional companies so have to cover my harris and do things a little different from your average tag holder.
And whilst we're on the subject I WISH NOMINET WOULD FINE 123-REG, this uesless inept company needs to learn somehow.
Cheers
