DC Blox Footprint Expands to Nine Tracked Facilities as Southeast Capacity Map Gains Three New Sites in 30 Days

## DC Blox adds three sites in 30 days

DC Blox now operates **nine tracked facilities** in DC Hub's live facility map, up from six a month ago. The operator added **Birmingham, Tennessee Regional, and South Carolina Regional** in September, all secondary markets where hyperscaler land plays and edge builds have accelerated since mid-2025.

The three additions bring DC Blox's corroborated footprint to **nine buildings** across Alabama, Georgia, Tennessee, and South Carolina—a concentration in non-Tier-1 markets where grid headroom and lower land costs have pulled colocation and edge workloads out of capacity-constrained metros like Atlanta and Charlotte.

## What it means for site selection

Secondary Southeast markets now carry **higher excess-power scores** than coastal hubs (Birmingham sits at 68/100 in the DCPI excess index vs. 41/100 in Atlanta). DC Blox's expansion into these corridors signals where operators see the next wave of hyperscale demand landing—markets with interconnection queue depth under 15 GW and substation capacity still available for fast-track builds.

For capacity planners evaluating Southeastern alternatives to Northern Virginia or Phoenix, the DC Blox footprint now offers a corroborated operator presence in markets that were off most institutional radars 18 months ago.
