Symantec AV Corporate 10.1 no longer updating

I know that Symantec AV Corporate 10.1 has hit the EOL, but it's been updating.  Well I just noticed our two servers are behind by about a week and when I attempt to update, it's says I have the latest version.  I just like to get confirmation that you can no longer get virus def updates for version 10.1 before I request approval to upgrade to the latest version.
