The record, newest first

  1. The North Texas Heritage Association, a residents' group, filed suit in the 271st District Court; its petition claims the county broke the Open Meetings Act during the review and asks the court to block any abatement until the county complies. (Jacksboro Herald-Gazette, July 17, 2026)

  2. The abatement hearing was taken off the agenda because the legally required newspaper notice had not run; it was reset for July 27. (Jacksboro Herald-Gazette, June 2026; Fort Worth Star-Telegram via GovTech, June 8, 2026)

  3. At a community meeting in Perrin, CyrusOne described a 250-acre, 144 MW site, a $600 million investment and a requested 30% county abatement for 10 years. (Jacksboro Herald-Gazette, June 8, 2026)

  4. Wise County commissioners unanimously asked the Legislature to set safeguards for large data centers or let counties regulate them, as the Jack County campus was proposed just across the line. (Wise County Messenger, March 10, 2026)

  5. The Wise County Messenger reported the plan: about 300 acres on Texas 199, eight structures, at least 144 MW and as much as $2 billion; residents had started a petition seeking road and environmental agreements. (Wise County Messenger, Feb. 25, 2026)

  6. CyrusOne, through C1 Jack I LLC, applied to Jack County for a property tax abatement; the county later scheduled a hearing on a reinvestment zone and abatement agreement. (Jacksboro Herald-Gazette, June 2026; Jacksboro Herald-Gazette, June 8, 2026)
