Extent: MCS Linux remote-login services; DS-Filestore SFTP service. Impact: Each server will be rebooted. We will reboot each of these servers between 17:30 and 19:00 on Wednesday 10 October to apply routine software updates. Users connected to a rebooting machine will be given a few minutes notice to save their work, then disconnected while the server updates itself. We will stagger reboots so that at least one server will remain available for new connections throughout the maintenance period.

We will apply a major software upgrade to each of the MCS Linux remote login and SFTP servers between 17:30 and 21:00 on Wednesday 26 September. Users connected to these machines will be given a few minutes notice to save their work, then disconnected while the server upgrades itself. We will stagger reboots so that at least one server will remain available for new connections throughout the maintenance period.

The new 2018–2019 build of MCS Linux is now feature-complete and will start being deployed University-wide by Information Services today, so that it can be tested by course-givers and end-users prior to the start of term.

Extent: Certain online forms for user administration. Impact: The forms will be unavailable for some or all of the above period. We will be updating the OS on the server that provides certain forms for applying for new services. This will mean that these forms will not be available, and that the contents of part-filled forms may be lost.
