- The termination of the WMS service had been announced - with a drain (i.e. not accepting new jobs) planned to start on 1st February. However, as the WMS is not being used by VOs at the moment and security patches need to be applied urgently the drain was brought forward and started this morning (10th Jan).
- Other security patching done or underway.
