Communauté urbaine du Grand Reims

Grand Reims, also known as Communauté urbaine du Grand Reims, is a French intercommunal structure that groups together the city of Reims and its surrounding communes. It exercises competencies transferred from its member municipalities in areas such as urban planning, economic development, housing, and environmental management. The organisation coordinates public transport services and promotes regional attractiveness for businesses and residents. Its actions are aimed at fostering cohesive development across the Grand Reims agglomeration.

Grand Reims operates within the Grand Est region of northeastern France, serving a territory that includes the historic city of Reims and neighboring communities. As a public establishment for intercommunal cooperation, it pools resources and expertise to deliver services that individual communes might struggle to provide alone. The structure enables joint decision‑making on major infrastructure projects and strategic planning initiatives. Its role positions it as a key actor in local governance and regional policy implementation.

In September 2024, Grand Reims experienced a distributed denial‑of‑service attack claimed by the pro‑Russian hacker group NoName057, which temporarily rendered its website inaccessible alongside several other French institutions. The attack was motivated by political opposition to France's support for Ukraine and did not result in any data breach, though it caused prolonged service disruption. Technical teams worked to restore access while the group framed the action as part of a broader political warfare campaign. This incident highlights the cybersecurity challenges faced by public sector entities in the current threat landscape.
