delay between activation email and RHN recognizing new subscriptions?

Got the email today:
The Red Hat subscriptions recently purchased for this account are now  
available for download and are immediately accessible through Red Hat  
Network. The information and resources you need to access Red Hat  
Network and get started with your subscription can be found in the Get  
Started Now section below.

However, following the link for the new subscription to get  
Installation number returns:
"We're sorry. That subscription is unavailable."

Neither the RHN or Redhat Customer Center have information on the new  
subscriptions yet. How long does it normally take for things to catch  
up?

Thanks,
