We track 26 datacenter sites in Maryland, deduplicated from 32 building permits and public facility records. Of those, 13 are operational and 13 are under construction. Facility directories report different totals because they count colocation suites and carrier hotels differently, so treat this as what we can evidence from public records rather than a definitive census.
13 sites in Maryland have permits indicating construction is under way. Because this comes from building permits rather than press releases, it reflects work that has actually been filed with a local authority.
11 named operators appear in Maryland, including Agile Data Sites, Amazon / AWS, Microsoft, Lumen, Zayo Group, AiNET Corporation, TierPoint, AiNET. 64% of sites nationally name an operator; the rest are permits filed by an LLC or contractor we could not resolve to a parent company.
