The theory behind CSA is that it is needed only for configuration and that maintenance can be scheduled around that activity. Taking it down is supposed to have no impact on operations.

When will we get a multi master CSA system? One CSA only is a big limitation and prevents us from connecting bigger = networks together. It's still impossible to keep one CSA server 24 h x 265 days alive = because also an CSA server requires an backup and other maintenance = procedures. But what happens with people and scripts that work and run = in this moment?=20 That is "easy" to manage in little networks but nearly impossible in big = networks. Ask the fileserver admins in your company how painful it is to = explain that a server needs to be shutdown. No one loves that and every = user hates the admin who done it.
