"On August 1st, 2011 Google transitioned the INUMC account to the new infrastructure for Google Apps accounts, a change that makes over 60 additional Google applications like Google Places, Google Reader, Picasa Web Albums and AdWords accessible with Google Apps accounts.

End users will see a notification about this change the first time they sign in after the update, they will also be asked to verify that they understand there has been an infrastructure upgrade.

If you have additional questions about this transition, we encourage you to explore our Help Center documentation for end-users."

Here is a link to the end user documentation.
