The servers used by the SRB systems require an update of their operating
system's security patches. This is for precautionary reasons, to keep
the operating system up-to-date and secure.
The servers will be updated at 9am on Tuesday 30th January and will be
unavailable for 30 minutes. During that time all SRB systems will be
unavailable. This affects BBSRC, Diamond, AHDS and Isis, plus the
testing and development systems.
