wlcg-operations
list.
- You can contact the
wlcg-ops-coord-chairpeople
list (at cern.ch
) if you do not manage to subscribe.
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 Geneva time until 15:20, exceptionally to 15:30.
- The SCOD rota for the next few weeks is at ScodRota
- 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.
