Calculated completed route mileage
Your network should be invisible.
Until you need us.
Uptime. Or your money back.
For eligible contracted services, the remedy is defined in the service agreement so the promise can be evaluated before signature.
Understand the promiseWhite glove means fewer handoffs and a named owner.
A technical lead stays with the route from feasibility through delivery. After turn-up, 24/7 monitoring, defined escalation, and proactive communication keep ownership clear.

through the Mid-Atlantic.
DRDI’s completed footprint combines the core Washington–Baltimore alignment with connected Central Maryland routes. Every displayed mile is calculated from the completed linework supplied by DRDI.
Protected by design
Entirely underground, with a minimum three-foot burial profile and controlled infrastructure access.
Capacity without compromise
Sixteen ducts with 864 fibers per duct support dedicated strands, conduit control, and future expansion.
Operational accountability
Qualified delivery in approximately 30 days, backed by continuous monitoring and a named escalation path.
What the network looks like before it disappears.
The best infrastructure becomes quiet after turn-up. These selected field images show the civil work, organized pathways, and maintainable underground access that make that possible.



Four facilities.
No status ambiguity.
Connected locations are available for qualification today. Planned Baltimore endpoints remain clearly marked until construction is complete.
Choose the layer
you need to control.
Each solution page answers ownership, optics, lease and IRU structure, capacity options, construction, maintenance, delivery, and pricing questions.
Dark Fiber
Control the optics, encryption, protocols, and upgrade cadence over a tested physical path.
Private Conduit
Reserve a dedicated duct structure and define cable ownership, access, and maintenance by agreement.
Custom Network Builds
Route engineering, permitting, construction, testing, handoff, and operations coordinated as one project.
Different buyers.
Different failure assumptions.
DRDI’s industry pages begin with how the network will be used, which layer the customer needs to control, and what the physical route must prove.
Data Centers & Colocation
Interconnection without hidden path assumptions.
Hyperscalers
Regional capacity built for long planning horizons.
AI & High-Performance Computing
Infrastructure for sustained data movement.
Enterprise
Private infrastructure for connected operations.
Finance
Physical route control for critical transactions.
Federal & Public Sector
Control, documentation, and accountable delivery.
Healthcare & Research
Private capacity for critical and data-intensive work.
Education
A regional foundation for connected learning.
Carriers & Managed Service Providers
