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

        Several discussions with Martin Bly, plus Mike Jones and Rob Metcalfe from DI this week, concerning the IPv4 slow transfers to the batch farm. We tried a few tests with changes to MSS size and packet size. We have more plans to gather data this week.

        Trying to get the tape approval and Echo dump processing scripts running on the new VM provided by fabric and George. Then the old machine - lcgvo06 can be retired and myproxy running there can be shut down.

        Ready to turn off the Phedex agents at RAL today. Waiting for the OK from US colleagues.
