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.
