date_projected_earliest_first_structures

string

Projected date first visible structures should appear under the FASTEST historical build pace: the unit’s projected online date (startup_date) minus 114 days. Read as the latest first-structures date still consistent with hitting the projected online date. Null when startup_date is missing/unparseable, or the unit is Operational and was never tracked.

Date of which the data center status was changed to under construction

2025-05-29

days_iir_minus_vulcan_earliest_online

object

The difference in days between the IIR startup date and the Vulcan earliest date

139

days_iir_minus_vulcan_latest_online

object

The difference in days between the IIR startup date and the Vulcan latest date

string

Observations or relevant data center comments after reviewing satellite images

land cleared

owner_name

string

IIR owner of data center

CloudHQ LLC

3714950-2696411

total_wpi

number

Cumulative Weekly Progress Indicator — running sum of the unit’s weekly_progress_indicator across all observed vintages up to and including this row. A construction-momentum measure; ~56 is the median total at completion. 0 when the unit has no WPI observations yet. Present on every vintage row (half-point increments occur because pre-first-structures weeks are half-weighted).
