300 facilities across 195 cities and 142 operators. Every value comes from a named public page, and capacity that is announced or under construction is never merged into what is running.

Bubbles are placed at the city centroid, not at a facility address: the catalogue releases location at city granularity. Bubbles with a solid edge are sized from reported capacity; those with a dashed edge from a figure derived off the facility’s own reported dimensions. A derived figure sizes a bubble and nothing else — it enters no total, ranking, or statistic anywhere on this site. Planned capacity is not operating capacity. The map plots 8,944 facilities across 3,987 cities; a campus is plotted once, at the campus. Division shading covers the 9 of 300 facilities whose recorded region matches a division name. An unshaded division means the catalogue records no matching region for its facilities, not that it holds none — every facility is still plotted by city.
By development stage
By facility count: 268 in service, 6 under construction, 21 planned, 5 stage not specified. 132 of the 300 report a capacity figure. Country capacity totals are published for the ten largest markets by capacity in service.
Data center cities in France
20 cities hold 3 or more catalogued facilities or a published capacity. A further 174 facilities sit in 144 locations with one or two each, all on the map above. 26 facilities have no published city.
Reported capacity is shown for the cities whose figures the release publishes; a dash means the city’s capacity is not published here, not that it has none.
