Make a simple model for notifications and use that on your front page
to notify upcoming maintenance breaks. I also use this style to inform
updates done etc. The model could be something like this:

class Notification(models.Model):
notification = models.TextField()
show_from = models.DateTimeField()
show_until = models.DateTimeField()

def __unicode__(self):
return self.notification

Put notifictions =
Notification.objects.filter(show_from__lte=datetime.now(),
show_until__gte=datetime.now()) into your template and show the
notification list there. Use apache to show the actual maintenance
break message when the site is down.

One approach is to use middleware, and in the middleware check:
if request.method == 'POST' and email_is_down():
return error page.

You could also use a default context processor which puts
posts_allowed variable in the context and then in base.html have {% if
not posts_allowed %} Technical problems... saving not allowed {% endif
%}. You could also wrap your submit buttons in {% if posts_allowed %}.
Maybe disable also the edit links...
