March 24, 2026
Digital Realty Trust
This is located in a former World War II submarine base known as Martha. Abandoned for decades, this unusual building was built to be virtually indestructible – its specifications include terraced reinforced concrete to a thickness of 5.5 metres, the ability to withstand 10-tonne bombs, a length of 250 metres and a 12-metre high surrounding wall. The result is an architecturally unique structure that houses a 16.5-megawatt data centre and approximately 7,100 square metres of fully equipped IT space to be delivered in three stages. This first phase, comprising approximately 2,300 square metres, will be followed by two additional phases scheduled for delivery during 2021.
MRS3 is situated adjacent to the MRS2 data centre and will benefit from the dense connectivity throughout the campus. As is the case for all Interxion’s data centres,
MRS3 will benefit from 100% renewable energy sources. Uniquely, MRS3 and subsequent data centres will benefit from cooling from an unused water source at 15°C drawn from the former Gardanne mines, which will be available throughout the year. The heat drawn off will be available for heating purposes for homes and offices in the new Euroméditerranée districts.

Digital Realty Trust is a data center public REIT that owns and operates facilities in the United States and Europe. The company provides colocation and interconnection services and develops large multi‑tenant data centers for enterprise and cloud customers.
