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;

- Whenever a particular topic needs to be discussed at the operations meeting requiring information from sites or experiments, it is highly recommended to announce it by email to the
wlcg-scod
list (at cern.ch
) to allow the SCOD to make sure that the relevant parties have the time to collect the required information, or invite the right people at the meeting.
