---++ General Information
   * The purpose of the meeting is:
      * to report significant operational issues (i.e. issues which can or did degrade experiment or site operations) which are ongoing or were resolved after the previous meeting;
      * to announce or schedule interventions at Tier-1 sites;
      * to inform about recent or upcoming changes in the experiment activities or systems having a visible impact on sites;
      * to provide important news about the middleware;
      * to communicate any other information considered interesting for WLCG operations.
   * The meeting should run from 15:00 until 15:20, exceptionally to 15:30.
   * The SCOD rota for the next few weeks is at ScodRota
   * General information about the WLCG Service can be accessed from the [[WLCGOperationsWeb][Operations Web]]
   * Whenever a particular topic needs to be discussed at the daily meeting requiring information from site or experiments, it is highly recommended to announce it by email to wlcg-operations@cernSPAMNOT.ch to make sure that the relevant parties have the time to collect the required information or invite the right people at the meeting.

Christian mentioned that NDGF is getting frequent tickets about missing files from the ATLAS shifters, which was due to the Rucio+FTS problem reported in the previous weeks and now solved. NDGF cannot do anything about that and it's not a site problem. David said that ATLAS is aware of that and will tell shifters not to open any ticket to sites for files from a list of known missing files.
