Colo-X analysis
Iron Mountain LON-1 was originally designed and built as a private data centre for Credit Suisse, who occupied half the site’s 6 data halls. It was acquired by Iron Mountain in a US$100m transaction of this site and another in Singapore in October 2017. Since then Iron Mountain have fitted the remaining vacant space and it is now fully let, primarily to Credit Suisse who remain in situ and another large customer, believed to be Logicalis. Logicalis previously ran their own data centre on nearby Buckingham Avenue, now the site of Iron Mountain LON-2 due to open Q4 2023.
Retail colocation users, looking for part-racks, racks or caged areas should consider other facilities on the Slough Trading Estate – contact Colo-X for the best nearby options.
Facility description
Iron Mountain are a huge American listed REIT, real estate investment trust, capitalised at some USD$15bn with 2021 sales of USD$45bn. The company operates 95m sq ft of real estate globally, most of which is for their long established document storage business.
Iron Mountain’s data centre division operates 19 sites in 16 countries, with 190MW of existing capacity across the US, Europe, Singapore and India, with a further 175MW under active development. Their European data centre development began with the October 2017 purchase of this site and was then further enhanced with the May 2018 purchase of Amsterdam based Evoswitch for USD$235m.
As with with most large scale data centre providers, Iron Mountain appears to now be focussing on a wholesale data centre model, selling large scale capacity to large users, on long terms leases or contracts. The forthcoming LON2 facility, on nearby Buckingham Avenue, offering 27MW, is understood to already be fully let to a single tenant.
Credit Suisse first acquired this site in 2006, at the height of the boom for demand in London data centre capacity when supply was extremely limited and buyers, especially from the financial services sector, were desperate to secure space to meet new regulations. Credit Suisse was not alone in significantly over-procuring. The Iron Mountain LON-1 data centre is a single storey structure with six data halls of 887 sq m or just under 2MW each.
