Finland · 1 project · Last reported
Summary
DayOne's Form F-1, filed October 5, 2026, reports that as of September 20, 2026 all 281 MW of Bookings at its two Greater Helsinki campuses, in Lahti and Kouvola, are Capacity Under Construction: planning, core and shell construction and MEP fit-out are actively underway, and the capacity is not yet ready for service. DayOne's Lahti campus is the Kiveriö site. The filing does not allocate capacity between the campuses; September 20 is its stated as-of date, not a site inspection. evidence

- Precision scope
- Official provider-supplied reference point for the exact permit-bound cadastral parcel, used only to locate one DayOne Kiveriö campus. Not a calculated centroid, survey, entrance, active-work extent, building footprint or asserted complete campus boundary. The parcel and reference point are not reused from the rejected road, wholesaler or service-area coordinates.
- Horizontal uncertainty
Not reported
No selected source quantifies this reference point's positional accuracy. Transformation-operation accuracy of 1 metre and numeric precision do not establish survey accuracy.

A locator places the site on the map. It is not a building footprint, a construction extent or a surveyed boundary unless the use scope is an official boundary, and even then it is a parcel or permit boundary.
Evidence
Sources are linked, not redistributed; each keeps its own terms. An archived copy is a lookup for the Wayback Machine capture nearest the retrieval date and may be unavailable or differ from what was reviewed. Each hash states what it covers; imported factual records are not publisher-page captures.
