Photoshop :: CS6 Subscription Activation

I was wondering if it is standard behaviour for my PS CS6 subscription to require me to log in to Activate the license EVERY time I use it? I thought that one it was activated, PS only checks the Activation every 30 days. Once I log in the activation works fine, however if for any reason my internet connection was not available, it would seem that I would not be able to use my copy of PS.
 
I realize that that would happen even if the check was every 30 days, but that would only be a possible issue once a month, not every day!
