Authentication: Outage manager
This is a Moodle plugin which makes the student experience of planned outages nicer, and provides extra tools for administrators and testers that help before and after the outage window.
The main idea is that instead of an outage being a very boolean on/off situation, this plugin creates the concept of graduated outages where at predefined times before an outage and after, different levels of warning and access can be provided to students and testers letting them know what is about to happen and why.
If you need support for Moodle 2.x ...
... you can still use this plugin but you will need to manually set up an additional local plugin contained, for more information please refer to: https://github.com/catalyst/moodle-local_outage
