Dear All,
The Moodle system stopped working at around 10:00am. It is back online at around 11:25am.
The outage was caused by unscheduled service updates in 3 of the servers in our LXD Container Cluster. As a result, the servers refused to talk to each other and all the services hung!
We will change the configuration of the concerned servers so that unscheduled service update will be prohibited.
My apology for any inconvenience caused.
Thank you!
Dr Terry Ng
Director of Information Technology
