I imagine it's possible in principle (and quite likely in practice) for
recently changed items to get different answers from the whois database
server(s) and the root servers. And, *especially* in the case of changes,
the old data can be cached for quite a while by any non-root server that
happens to have acquired it before the change. There's absolutely no "push"
mechanism in the DNS aside from (optional) notification of secondaries about
changes made at their zone's master, and that won't affect the majority of
DNS servers. You may be seeing the effect of a normal TTL keeping the old
data in caches - a week is not an unusually long TTL for most records.
How are you probing the servers? For finding out who actually has what
information, you really need to drop down into a diagnostic tool such as
nslookup or dig. Your description makes it sound as if you're just sending
normal end-user queries, which is the least controlled and generally least
informative way to find out what's really going on.
If you would care to share the spelling of the mysterious domain you might
get back an annotated example of these things. :-)

I looked at Granite Canyon around a year ago, when I was first seriously
playing with setting up a registered domain. Sometimes I did, anyway: IME
their web site was a hit or miss proposition, and that didn't inspire a lot
of confidence in me about their DNS service's reliability.
