Colo-X analysis

CyrusOne LONI (or LON1) was originally opened by Zenium in early 2017 as a two storey, wholesale data centre, designed to be sold to just a few or even a single large occupier.

CyrusOne own and operate five London data centres, of which four are on the Slough Trading Estate and one in Hayes (acquired from Infinity in 2015), along with a legacy suite in the DRT Woking site.  In total CyrusOne provide some 67MW of capacity in the UK market. They are very much a wholesale data centre operator, selling large scale solutions to the largest buyers under long term contracts or leases.

Retail colocation users, taking part-racks, racks or caged areas should consider other facilities within the Slough Trading Estate – contact Colo-X for best options.
