I'm in a similar situation. A service getting about that many hits per day, with the majority of the traffic being during the day. We have a few servers behind a load balancer to help with the peak traffic. Luckily, traffic peaks during European daytime, so when I'm in the office (USA), it's the low period. I can pull one of our servers out of the load balancer, push the update, put it back in and watch the responses. If things don't blow up, rinse and repeat. It's feels pretty hacky to me though, so I've been recently reading up on Fabric and deployment patterns for Django, great timing with this article being posted!
