I've a strange issue on my OpenStack prod system, suddenly. My Env(Havana/Ubuntu12.04) runs since weeks with small problems but not really unstable. Since 30 mins any created user can't see the external network:

That worked since beginning and suddenly no more. I'm now playing with the really bad workaround to make this network shared. Normally should see each user all network with: router:external=True

Do anyone have this issue too ? I've no idea
