Interxion, the European data center giant now part of San Francisco-based Digital Realty Trust, has converted a WWII German submarine bunker (which the Nazis never finished or used) in Marseille into a data center. The site officially came online in July 2020. To learn more about the project and its importance on the global interconnection map, read our feature here.
