Harbor Link announced an underground fiber expansion into CoreSite’s DC2 data center in Washington, D.C., extending its Mid-Atlantic network to DC1 and VA facilities. The project boosts fiber diversity and low-latency interconnection for enterprises and hyperscalers; as CoreSite is an American Tower company, the expansion could support AMT’s data-center strategy and tenant demand in these key markets.
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.
Bullish for AMT in the near term as CoreSite benefits from expanded interconnectivity; 6–12 months may see upside.
