Harbor Link expands underground fiber into CoreSite DC2, signaling AMT data-center ecosystem growth

Jul 14, 2026, 8:39 AM EDT1 sourcesAI-analyzed
Why it may matterVerify against the original reporting

The expansion reinforces CoreSite’s interconnection strength and tenant appeal, potentially improving occupancy/lease economics. As CoreSite is an AMT subsidiary, positive tenancy trends and higher connectivity depth can translate into higher recurring revenue and potentially an uplift in AMT’s valuation over the medium term, particularly if hyperscale demand accelerates in DC/NOVA.
