The demonstration site may occasionally be taken offline for brief periods of maintenance at any time during UK weekday working hours, sometimes with only fairly short advance notice given (usually noted below).
If you see a maintenance downtime alert on the demonstration site, please make sure that you logout as soon as possible.
Please note that the website is also offline for automated overnight maintenance for approximately 15 minutes between 04:00 and 05:00 local time every day (timezone GMT/UTC during northern winter, BST/UTC+1 during northern summer).
There are no additional maintenance periods scheduled at present.
