A question about sites downtime updates
If you have any significant traffic in time that is measured in microsecond it's probably best to push new changes to your web servers one at a time, and remove the machine from load balancer rotation for the moment you're doing the upgrade there.
I've a server when I run a Django application but I've a little problem:
when with mercurial I commit and pushing new changes on the server, there's a micro time (like 1 microsec) where the home page is unreachable.
I have apache on the server.
How can I solve this?
