Service Areas

Business Fiber Across California

Vast Networks operates a privately owned fiber network across California, with the deepest presence in the Central Valley where the company is headquartered. These are the markets we can describe honestly — and the process for confirming what is possible at your specific address.

California markets

Each market page covers the local network position, the industries that shape connectivity demand there, the services available, and the questions businesses in that market actually ask. None of them claim service at a specific address.

Service availability depends on location, network proximity, capacity, and engineering review. Share an address and we will confirm what can be delivered there.

Frequently asked questions

How do I know whether Vast Networks can serve my address?

Send us the address and a bandwidth target. An engineer checks it against the network and tells you what can be delivered there, whether construction is involved, and what the timeline looks like. We do not answer availability from a coverage map, because a map cannot tell you what the last stretch to your building actually requires.

Do you only serve the Central Valley?

The Central Valley is where the network has the most depth and where our headquarters and engineering staff are based, but the fiber network extends across California. The market pages here cover the areas where we can describe local context honestly; if your location is not listed, ask anyway.

Why are some California cities not listed?

Because we only publish a market page when we can say something specific and true about serving that market. Adding a page for every city in the state would be easy and useless. If you are outside the listed markets, an availability review is still the right next step.

Can you connect sites in different markets to each other?

Yes — regional transport up and down the Valley corridor is a core capability. A point-to-point circuit or a wavelength between two of your sites gives them a private path that never touches the public internet.

Check fiber availability at your address

Send us the address and a bandwidth target. A California-based engineer confirms what can be delivered there, what it involves, and how long it takes.
