Some unfortunate timing means that there is university-level system maintenance scheduled for 13-15 December at both Birmingham and Warwick, which means that we have to shut down all of the underlying CLIMB infrastructure. All CLIMB services at these sites will be shutdown, so instances will be inaccessible during this period.
The specific times of the shutdowns are:
Birmingham - 1600 on the 13th December until 1300 on 14th December
Warwick - 0900 on the 13th December until 1700 on the 15th December
As instances will have to be shutdown, any jobs running will be stopped and will have to be restarted when service is restored.
Service at Warwick is on track to be restored by the end of the day today
If their current region is set to Warwick, users may experience gateway timeouts at https://bryn.climb.ac.uk until Warwick is running. We expect this to be resolved by the end of the day, but if you need access to https://bryn.climb.ac.uk before then, please send me a direct message and I can fix it so that you can use either Birmingham or Cardiff.
When you start your instances again, please check that any attached disks are mounted in the correct place using the disk filesystem (df) and list block devices (lsblk) commands.
