Well, I'm no Dataguard expert, but, seems to me, if stand by site goes down, primary would remain up and as soon as standby was restored, log shipping would begin playing catch up. Also, if you're in maximum protection mode, then at some point, you'd run out of space to queue up archivelogs to be shipped to standby, at which point primary would hang....
