Iron Mountain Data Centers·Operating·36 MW
Iron Mountain runs two data centers in Slough, LON-1 and LON-2, with a combined 36 megawatts of power across more than 35,000 square meters. LON-1, at 724-729 Dundee Road, was originally built for one of the world's largest banking institutions before Iron Mountain took it over. LON-2 is a newer, greenfield building nearby at 110 Buckingham Avenue.
LON-1 alone holds 8.75 megawatts of that total; the site sits west of the M25 in Slough's data center corridor with an on-site link to the LINX internet exchange. A third building, LON-3, at 111 Buckingham Avenue, is being held for future development and is not yet built.
