        VO Liaison CMS 1m
        Speaker: Katy Ellis (Science and Technology Facilities Council STFC (GB))

        No particular problems for CMS over Christmas. CMS took on some additional cores dropped by ATLAS. 

        We are still not writing to RAL tape, which is still full to pledge.

        Job efficiency has been very up and down.

        I have asked DI what plans there are for e.g. enabling jumbo frames in the firewall, but no reply yet.
