The record, newest first
Bluebird's page describes the site as self-sufficient, with 6 MW of off-grid power, three diverse utility feeds and technicians available 24/7. (Bluebird Fiber, June 30, 2023; Bluebird Network, Feb. 2022)
City Utilities of Springfield's SpringNet sold its 56,000 sq ft underground data center to Bluebird Network, which renamed it Bluebird Underground. (Bluebird Network, Dec. 5, 2014; REjournals, April 4, 2017)
Conflicts and open questions
- Under 50 MW.
- The 6 MW is off-grid on-site power, not stated IT load, so mw is left blank.
- Size: Bluebird's 2014 release gives 56,000 sq ft for the whole facility; left blank because current size is not stated.
- REjournals (2017) gives an $8.4 million price and Dec. 4 approval / Dec. 5 closing without a year; Bluebird's release is dated Dec. 5, 2014.
- A DatacenterDynamics report on a later expansion (about 29,000 sq ft of white space) was opened but is undated, so it is not used.
- No street address in opened sources; coordinates are a rough northwest Springfield point.
