Google Apps has had various problems this morning including inability to access GMail for a period of time. The problem appears to have started at approximately 8:20 AM. Some people report they still cannot access some Google Apps. If you have already logged into GMail it appears to still be functioning as of now (9:00 AM).
We are trying to contact google support to address the issue.
Update 9:21 AM: Google has updated their status page with more information. Click on the small dots under today’s date: http://www.google.com/appsstatus
Update 10:57 AM: Google reported at 9:51 that service was being restored. Service appeared to be back for everyone by approximately 10 AM.
