For Mason County businesses that have been running on slow or unreliable internet, the infrastructure picture is finally changing. Mason County PUD 3 is midway through a multi-year fiber buildout that is reaching rural and semi-rural commercial areas that private carriers have never touched.
If your business depends on internet — and most do — here is what you need to know.
What Gigabit Fiber Actually Does for a Small Business
The headline number is 1,000 Mbps download and 1,000 Mbps upload — symmetrical gigabit. But for most small businesses, the upload speed is what matters most. Legacy DSL and cable connections are asymmetrical: you get fast downloads but slow uploads. That means uploading files to clients, backing up to the cloud, running video calls, or processing point-of-sale transactions all compete for the same limited upstream pipe.
Fiber eliminates that bottleneck. A business that was previously struggling to host a video call while running cloud-based accounting software can now do both simultaneously — along with a dozen other tasks — without degradation.
Which Areas Are Coming Online and When?
PUD 3 connected Pacific Ridge (March 18), Arcadia Shores (March 25), and Fern Way (March 26) in March 2026. The Cloquallum Communities Fiberhood — serving 680+ addresses — is working through individual connections now with a full completion target of October 2026. The Three Fingers Fiber Project, funded by a federal ReConnect grant, is also in its final connection phase with an April 2026 project deadline.
If your business is in one of these areas, fiber infrastructure is likely already built to your property. Visit pud3.servicezones.net to check your address and schedule an installation.
The Open-Access Model: More Providers, More Competition
PUD 3 runs an open-access network — the utility builds and maintains the fiber, but multiple competing retail internet service providers can deliver service over the same infrastructure. For businesses, this matters because it prevents the lock-in and price inflation that happens when a single ISP controls access in an area.
You choose your provider, and providers compete for your business. That’s the opposite of the single-provider rural internet model most Mason County businesses have lived with for years.
What This Means for Remote Work and Business Attraction
Mason County has long faced a disadvantage in competing for skilled workers and remote-friendly employers who have historically required Puget Sound proximity because of internet infrastructure. As fiber reaches more of the county, that calculus changes.
A home-based Mason County worker who can now reliably run video calls, access corporate systems, and upload large files at gigabit speeds doesn’t need to commute to Tacoma or Bremerton to be productive. And employers who might have passed on Mason County office space because of connectivity concerns have fewer reasons to do so.
The economic development implications of the PUD 3 buildout extend well beyond individual households.

Frequently Asked Questions
Can businesses get fiber internet through PUD 3 in Mason County?
Yes. PUD 3’s fiber network serves both residential and business customers. Commercial properties in fiberhood service areas can schedule an installation and choose a retail service provider from those operating on PUD 3’s open-access network. Check your address at pud3.servicezones.net.
What’s the difference between PUD 3 fiber and a private ISP like Comcast or CenturyLink?
PUD 3 is a public utility that builds and maintains the fiber infrastructure, then allows multiple retail internet providers to deliver service over it. Private ISPs own their own infrastructure and control pricing and availability. In rural Mason County, private ISPs have historically underinvested — PUD 3’s public model is reaching areas that private carriers have declined to serve.
Is PUD 3 fiber available for commercial properties or just residential?
PUD 3’s fiber is available to any address within a completed fiberhood, including commercial properties, home-based businesses, and farms. Contact PUD 3 directly to confirm eligibility for your specific business address.
How does PUD 3’s open-access fiber model benefit business owners specifically?
Because multiple internet service providers compete on the same infrastructure, businesses can shop for price, contract terms, and service-level agreements rather than accepting whatever a single provider offers. This competitive dynamic tends to produce better pricing and service quality than monopoly-provider markets.
