General site services
As always, in addition to the Fire and Rescue service (+41 22 76) 74444, the Security service remains operational every day (24/7) and can be reached at (+41 22 76) 78878.
SCE department services that do not depend on continuous human presence will remain available, although at a reduced support level. In general, the response time for common issues will be half a day (but this is not guaranteed). To report urgent infrastructure issues during the annual closure, call the CCC TI operator at (+41 22 76) 72201.
Other services requiring human presence (such as Service Desk, CERN hostels, car sharing, shuttles, cleaning services, etc.) will not operate during the end-of-year closure
For more information, please consult the CERN Service Portal.
In addition, please note that the heating on the Meyrin and Prévessin sites will be switched to low-heat mode to maximise energy savings during this period of low occupancy. This will lead to a slight drop in temperature.
Essential services provided by the IT department – including WLCG production services – will remain available.
Most problems will be dealt with on a best-effort basis only and the availability of specific services might be limited by the availability of other services. No interventions are scheduled – in case of a failure, there is no guarantee that services will be restored, and changes requiring on-site human intervention will not be possible.
Incidents will be listed on the CERN Service Status Board for Computing.
The Computer Centre Operator service will be available and can be reached at (+41 22 76) 75011 or by email to firstname.lastname@example.org, where urgent problems can be reported.
Suspected computer-security incidents must be reported to Computer.Security@cern.ch or (+41 22 76) 70500 as usual.
Please remember to shut down and power off any equipment in your office whose operation is not required during the annual closure.
