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 5 December 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.

An operating system crash in THUNDERBIRD-1, one of two servers that provides the linux.ds.cam.ac.uk Remote Login service, caused that machine to stop functioning this afternoon at around 08:50. We have rebooted the machine, and it is now functioning again as before as of 09:06. However, any processes that were running on it at the time of the crash have been lost. We apologise for the disruption, and will try to prevent this error from happening again.
