US colo firm Iron Mountain is to expand its Amsterdam campus.

An additional 10MW of capacity will be added to AMS-1, bringing the data center closer to its maximum buildout of 60MW. It presently offers 22.7MW of capacity with 17,000 sqm (183,000 sq ft) of space.

AMS-1 is located on a 23-acre site in Haarlem, a city west of Amsterdam. The company said in a LinkedIn post that this would be the first tranche of expansion.

The operator initially entered the Amsterdam market through the acquisition of Dutch colo EvoSwitch in 2018, taking over the AMS-1 site.

The American mushroom farm-turned-storage and colocation provider is rumored to be linked with another data center in the Haarlem area of Amsterdam. Scheduled for delivery around October 2026, this facility will be 11,000 sqm (118,400 sq ft) with a capacity of 10MW.

Iron Mountain manages more than 25 data centers worldwide. In Europe, it has facilities in Frankfurt, London, and Madrid.

The company recently made a foray into the MENA (Middle East and North Africa) market, taking a minority stake in MENA Digital Hub, Qatari telco Ooredoo’s data subsidiary. In April, it took ownership of Indian data center operator WebWerks and appointed Gary Aitkenhead, former SVP of Equinix’s EMEA operations, as the company’s EVP and GM of data centers.

These moves come off the back of Iron Mountain’s FY 2024 results, which saw its data center division report $620m in revenue, up 25 percent year-on-year.

Most data centers in the Netherlands are located in or around Amsterdam. Other operators in the area include Digital Realty, Equinix, and CyrusOne. The city still feels the impact of the one-year moratorium on new data centers, which was imposed in 2019.
