Computers in BSL reboot automatically at 7.15 am each day. If you are working in BSL overnight, please be sure you have saved any work around this time as an unsaved file could be lost when the computer reboots. The system gives you a one-minute warning that the computer is about to reboot, but you might be temporarily away from the computer and miss this message. So be sure to save your work regularly to minimise the risk of losing it. This is good practice anyway.
