CDS News - Scheduled System Downtime   [updated 30 Apr 2013]

We allocate a fixed slot on Thursdays at 6:15pm for planned system reboots to implement standard operating system upgrades The Service should then be considered to be "at risk" for up to an hour. However we are unlikely to need to take the system down on most occasions. We will post details of planned reboots on the CDS homepage.

Reboots take only a short time. However those directly logged onto the CDS server will be disconnected, and the results of any active searches are likely to be lost. You are advised to avoid such activity immediately before reboots. Those accessing the Service using the web facilities are less likely to experience problems.

Sometimes we need to make major software or hardware changes where we have to take the system down for a period. Where feasible, these will be in the 6:15pm Thursday slot.
