Capacity evidence

Statements retain their dates, definitions and development scope. Do not add these rows together.

Claim / measurement	Scope and status	As of	Evidence and accounting
20.7 MW IT load	Advertised existing Amsterdam 1 campus critical IT capacity Operational · cumulative	2026-10-09	Reported claim ↗ Excluded from capacity totals. As-of is retrieval date of undated operator page, not commissioning date or measured consumption. Supports reported capacity above 5 MW.
40 MW IT load	Amsterdam 1 campus at full build-out Planned · cumulative	2026-10-09	Conflicting claim ↗ Excluded from capacity totals. Retrieval date of undated operator page. Full-build figure is not additional to existing capacity; conflicts with simple addition of brochure figures.
22 MW IT load	Additional capacity in buildings C and D Under Construction · incremental	2026-10-09	Conflicting claim ↗ Excluded from capacity totals. As-of is retrieval date only; brochure edition is explicitly March 2023, with no exact publication day. Construction status describes that edition and is not independently confirmed current. Do not add to 20.7 MW without reconciliation against 40 MW ultimate claim.
6 MW IT load	Initial phase-one capacity in original development announcement Under Construction · incremental	2018-03-28	Reported claim ↗ Excluded from capacity totals. Announcement date; phase one was scheduled for early 2019. Historical starting capacity, not current campus total.
39.6 MW IT load	Original ultimate campus design capacity, described as up to 39.6 MW Planned · cumulative	2018-03-28	Reported claim ↗ Excluded from capacity totals. Announcement date. Source states an upper limit; schema has no upper-bound qualifier, so exact records the stated design ceiling rather than guaranteed delivery. Later operator pages use 40 MW.
20 MW IT load	Phase one as described in PeeringDB facility notes Operational · cumulative	2025-09-26	Conflicting claim ↗ Excluded from capacity totals. As-of is record last-updated date, not necessarily the date the notes or capacity were revised. Differs from operator's 20.7 MW existing claim.
10 MW Unspecified power	Fully built-out power on opened industry specification page; campus/building scope unclear Unknown · unclear	2026-10-09	Conflicting claim ↗ Excluded from capacity totals. Retrieval date. Opened page differs from search extract and operator campus data; retained as an unresolved secondary claim.
