Last week a client phoned me out of hours because their self-hosted Moodle site had gone down. After checking the web server, MySQL, and Moodle, there didn’t appear to be any errors. After a while trouble-shooting, it turned out to be an internal DNS error. This is a good lesson, because if your Moodle server is working, and you just shut it down, start it up, and it’s not working, the most likely reason is something else such as network configuration.
