Following a previous message on the impact of the G7 summit on CERN activities, we are sharing additional information and links to keep you informed in real time.

Access

CERN’s operational activities will continue during this period.

To reduce the risk of congestion at the border, it is recommended to limit travel to CERN as much as possible when compatible with operational needs. Telework, and adapted working hours when on-site presence is required, are recommended for members of personnel in agreement with supervisors.

CERN is in contact with the authorities of the Host States to explore possible arrangements aimed at facilitating travel for collaborators whose presence on site is required (Gate E, inter-site tunnel, badges) and for children attending the Jardin des Particules.

Any exceptions or additional measures agreed with the authorities of the Host States will be communicated immediately once confirmed.

Nevertheless, any potential arrangements do not exempt users from avoiding or anticipating travel, as major traffic disruptions are expected in the Geneva area and queues of stationary vehicles may complicate reaching Gate E and the inter-site tunnel.

Campus Services

Most CERN Campus services remain open during this period, with some possible disruptions. For real-time information, please consult the status dashboard, which is available in English and French.

Stay informed

To ensure you receive the latest updates during the G7 period, please use the following channels:

• CERN Campus App: The CERN Campus App provides real-time updates, notifications, and practical information. We strongly recommend installing the app to receive immediate alerts and stay informed of any changes affecting access, transport, or services.
  • Download the app or use the web version
• Mattermost channel: Live updates and operational information will also be shared via the dedicated Mattermost channel.
