*Blocks follow a site's build-out over time; an expansion is a new block. A deal can span several blocks — picking a deal in the form prefills its remaining contracted capacity, net of what its other blocks already target. Power figures are recorded on the basis the source reported, IT load and/or gross.
**A block's capacity is taken to come online at its delivery end date (the actual date when one is recorded, otherwise the target); failing that at its delivery start date; failing that one year after its energization target. That resolved date is what the capacity estimates on the Sites & Capacity tab use.
*** Converted from the other basis with the PUE common metric (currently 1.3), because the blocks do not all state this one.
