Haarlem colocation campus with operational AMS-1 and expansion projects. Operator reports 13.1 MW current power, exceeding 5 MW without establishing an IT-load basis. Expansion naming and ultimate capacity require reconciliation.
Statements retain their dates, definitions and development scope. Do not add these rows together.
| Claim / measurement | Scope and status | As of | Evidence and accounting |
|---|---|---|---|
| 13.1 MW Unspecified power | Current AMS-1 power capacity Operational · cumulative | 2026-10-09 | Reported claim ↗ Excluded from capacity totals. As-of is retrieval date of undated operator page; power is not explicitly IT load or grid capacity. |
| 13.1 MW Unspecified power | AMS-1 total leaseable capacity Operational · cumulative | 2026-03-31 | Reported claim ↗ Excluded from capacity totals. As-of is Q1 2026 reporting period end. Leaseable MW corroborates operational scale but does not explicitly establish electrical basis; overlaps c1. |
| 10 MW Unspecified power | AMS-1 Phase 4 expansion Under Construction · incremental | 2026-03-31 | Reported claim ↗ Excluded from capacity totals. Quarter-end development table; expected completion Q2 2027. Marketing names a same-sized project AMS-2; relationship unresolved. |
| 20 MW Unspecified power | AMS-2 held for development Planned · incremental | 2026-03-31 | Reported claim ↗ Excluded from capacity totals. Quarter-end filing lists separately from AMS-1 Phase 4; do not equate to marketing's 10 MW AMS-2 without reconciliation. |
| 10 MW IT load | Marketing-named AMS-2 expansion building Under Construction · incremental | 2026-06-12 | Reported claim ↗ Excluded from capacity totals. Publication date; expressly IT-load facility with Q2 2027 readiness target. Potential overlap with c3. |
| 43.1 MW Unspecified power | Amsterdam campus at full build-out Planned · cumulative | 2026-06-12 | Conflicting claim ↗ Excluded from capacity totals. Publication date; ultimate campus figure, also on principal facility page. Conflicts with other operator ultimate-capacity descriptions; basis unspecified. |
| 30 MW IT load | AMS-1 campus at full build-out Planned · cumulative | 2026-04-12 | Conflicting claim ↗ Excluded from capacity totals. Publication date; body expressly says critical IT. Cannot reconcile with 43.1 MW unspecified campus total. |
| 14.1 MW Unspecified power | AMS-1 total potential capacity in location overview Planned · cumulative | 2026-04-01 | Conflicting claim ↗ Excluded from capacity totals. Displayed publication date, not commissioning date. Phase boundary and power basis unspecified; differs from other operator figures. |
| 22.7 MW Facility power | AMS-1 facility on operator campaign page Unknown · cumulative | 2026-10-09 | Conflicting claim ↗ Excluded from capacity totals. Retrieval date of undated page. Wording says MW facility but does not define metering boundary or operational timing; directory calls this live power. |
| 60 MW Unspecified power | 23-acre campus capacity on operator campaign page Planned · cumulative | 2026-10-09 | Conflicting claim ↗ Excluded from capacity totals. Retrieval date; directory labels same value fully built-out power. Conflicts with current 43.1 MW ultimate campus claim. |
| ≈11 MW Unspecified power | First location in historical EvoSwitch acquisition Operational · cumulative | 2018-05-30 | Reported claim ↗ Excluded from capacity totals. Announcement date; historical first-location existing capacity, not current capacity. Transaction also included a second site. |
| 27 MW Unspecified power | First location's historical total potential capacity Planned · cumulative | 2018-05-30 | Reported claim ↗ Excluded from capacity totals. Announcement date; excludes second location's 7 MW potential. Historical development scenario, not a current campus total. |
