What do you do during maintenance?

The answer to this question varies, but in general we use this time to perform maintenance on some of our critical systems.  Apply software updates, update server hardware, perform code releases which might otherwise impact posting negatively, etc.

Why do you need maintenance so often?

We schedule this monthly maintenance so that users are not caught unaware when we do need to use it.  We may not need to use our maintenance window every single time, and in those cases when we don't need it we will announce that the scheduled maintenance has been canceled using our Twitter account.
