Site Alert

The Site Alert module is a lightweight solution for allowing site administrators to easily place an alert on their site, for example for maintenance downtime, or any general informational message. Alerts have start and end date/times, and can be assigned a severity level. Messages are refreshed by ajax and not subject to site caching, so changes made in the ui will be automatically displayed to users without necessitating a cache clear. The module provides a custom pane (recommended) and a block for sites not using panels.
