Last virus def update 3 hrs ago

NIS 2012

Checked this morning and saw last virus def updates 3 hrs ago. So I ran manual live up date and got white list and antispam defs
But no pulse updates
So waited again 10 mins or so. Ran live update and got message no updates found
Tried this again several times with same results

Checked live update history and did not receive any updates that required reboot

Strange that there are no pulse updates

Anyone else experiencing this?
