A statewide fiber backbone, built and owned by Vast.
Vast Networks designed, built, and runs its own fiber across California — more than 5,000 route miles of it, reaching past the dense metros into the rural and agricultural regions most carriers leave behind. We own the physical plant rather than reselling someone else's capacity, so the network answers to our customers, not a wholesale supplier.
That independence shapes everything downstream. We choose the routes, set the standards, and upgrade on our own timeline — which is how we keep performance high, expansion steady, and the people who actually built the network close enough to pick up the phone.
-
Underground & protected
Buried plant that resists weather and accidental damage.
-
Diverse, redundant routes
Multiple physical paths engineered for resilience.
-
DWDM optical core
A backbone that scales from megabits to terabits.
-
MEF-aligned engineering
Carrier-standard design behind every circuit.
The infrastructure advantage.
Owning the network end to end isn't just a technical detail — it's what lets Vast move faster, support you directly, and put real guarantees behind your service.
One provider, end to end
Fiber connectivity and business voice from a single team on a single bill — no finger-pointing between vendors when something needs attention.
Engineers, not call centers
When you call, you reach the local people who designed and run the network — not an overseas tier-one script.
Scales without forklifts
Grow from megabits to hundreds of gigabits on the same fiber. More capacity is a configuration change, not a construction project.
Accountable performance
Service-level agreements with real financial remedies, backed by proactive monitoring that catches issues before you do.
Industries that rely on us.
Hospitals, school districts, growers, factories, and carriers all run on the same robust private fiber backbone.

California’s middle-mile backbone, and what it changes for fiber
Senate Bill 156 put $3.25 billion behind a public, open-access fiber backbone reaching across the state. Here’s what the middle mile is — and why it only matters once someone builds the last mile.

What “bandwidth” actually means on fiber
Speed is how fast data moves; bandwidth is how much can move at once. Fiber carries over a thousand times more of it than copper — here’s the physics, in plain terms.

How California’s public fiber became an operator story
The state turned on the nation’s largest public, open-access middle-mile network — 8,100 miles of it. But the backbone stops short of every front door on purpose. The rest is up to operators.
