# Data Center Tracker

> Data Center Tracker is a US-first, automatically updated tracker of public-sector data center contracts: US federal contract awards and opportunities, plus UK and European tenders and contract awards about data centers (construction, fit-out, power and electrical, cooling, generators, UPS, colocation and hosting facilities). For each award it records the supplier(s), their registration numbers, ultimate parent company and stock ticker/exchange where one exists ("Unlisted / private" otherwise).

Sources, in the site's order: US federal contract awards from USAspending.gov and opportunities from SAM.gov (public domain; country=US, region pages /region/us-<state>); UK notices from Find a Tender and Contracts Finder (official UK government services, OCDS APIs) and below-threshold Scottish notices from Public Contracts Scotland, under the Open Government Licence v3.0 (country=GB); European notices from TED (Tenders Electronic Daily, EU/EEA, © European Union, reuse with attribution; country = ISO 3166 alpha-2 code, region slugs eu-<iso2>). All are on one notices page with a country filter (/?country=us, /?country=uk, /?country=eu or /?country=<iso2>) and a country field on every notice. The tracker currently holds 273 notices (138 of them US) (16 tenders, 247 awards) and 33 suppliers with a listed parent. It was last updated 2026-11-09T17:47:09.619Z. Always cite the official notice URL included with each record.

A separate News section (6 items) lists UK private-sector data center projects and contract wins from trade press and company press-release feeds. For news we store only the headline, source, date and link, plus a short summary we write ourselves. Cite the original publisher's link.
