Present a maintenance page to visitors. Disables your application's web \
interface by writing a "maintenance.html" file to each web server. The \
servers must be configured to detect the presence of this file, and if \
it is present, always display it instead of performing the request.

By default, the maintenance page will just say the site is down for \
"maintenance", and will be back "shortly", but you can customize the \
page by specifying the REASON and UNTIL environment variables:

$ cap deploy:web:disable \\
REASON="hardware upgrade" \\
UNTIL="12pm Eastern Time"

Further customization will require that you write your own task.
