Dedicated fiber is the fastest path to dedicated, business-grade connectivity — with none of the operational overhead.
We design, install, monitor, and maintain the circuit end-to-end. You just plug in and go.
Identical upload and download from 100 Mbps-400/800 Gbps — built for cloud, backup, and voice.
Carrier-grade uptime with financial remedies, proactive monitoring, and guaranteed throughput.
Same-day bandwidth upgrades with no data caps and no overage billing — ever.
Dedicated fiber internet — often called Dedicated Internet Access, or DIA — is a private, business-grade connection that reserves a fixed amount of bandwidth entirely for your organization. Unlike shared broadband, cable, or coax, where capacity is divided among many subscribers in your neighborhood, a dedicated fiber circuit delivers symmetrical upload and download speeds that stay consistent no matter the time of day. At Vast Networks, every circuit runs across 5,000+ route miles of privately owned underground fiber spanning California, engineered for carrier-class reliability from 100 Mbps to 400/800 Gbps.
Most consumer and small-business plans are built on a contention model: the provider sells the same capacity to many customers and bets that they won't all use it at once. That's why "up to" speeds collapse during peak hours and why upload speeds are usually a small fraction of download. Dedicated fiber removes contention entirely. The bandwidth is yours alone, the connection is symmetrical, and performance is the same at 3 p.m. on a Monday as it is at 3 a.m. on a Sunday.
Modern business runs in both directions. Cloud applications, VoIP and video conferencing, off-site backup, large file transfers, and remote access all depend on a fast, reliable upload path — not just download. Symmetrical dedicated fiber gives you identical capacity in each direction, so video calls stay crisp, backups finish on schedule, and your team works from the cloud without the lag and jitter that plague shared connections.
A dedicated circuit is only as good as the guarantee behind it. Every Vast Networks dedicated fiber service is backed by a carrier-grade Service Level Agreement covering uptime, latency, packet delivery, and mean time to repair — with financial remedies if we miss the mark. Our California-based Network Operations Center monitors your circuit proactively, 24 hours a day, so issues are often detected and resolved before they ever reach your team.
If your operations depend on the internet being fast and available every minute of the business day, dedicated fiber is the most dependable foundation you can build on. It's the right fit for cloud-first and SaaS-heavy teams, real-time voice and video at scale, multi-site and campus environments, and any organization that simply can't afford the slowdowns and outages that come with shared bandwidth. We size, build, monitor, and maintain the circuit end-to-end — you just plug in and go.
Common questions about dedicated fiber internet access, speeds, SLAs, and availability.
Dedicated Internet Access is a private, business-grade fiber connection that reserves a fixed amount of bandwidth exclusively for your organization. Unlike shared broadband or cable, the speed you buy is the speed you get — 24/7, with no contention from other subscribers and identical upload and download throughput.
Our dedicated fiber circuits scale from 100 Mbps up to 400/800 Gbps, all delivered symmetrically. We size each circuit to your workload and offer same-day bandwidth upgrades as your needs grow — with no data caps and no overage billing.
Shared connections split capacity across many users in your area, so advertised "up to" speeds drop during busy hours and uploads are typically a fraction of downloads. Dedicated fiber gives you uncontended, symmetrical bandwidth that performs the same at 3 p.m. as it does at 3 a.m., backed by a financially guaranteed SLA.
Every dedicated fiber circuit is backed by a carrier-grade uptime SLA covering availability, latency, packet delivery, and mean time to repair — with financial remedies if we fall short. Our 24/7 California-based Network Operations Center monitors your circuit proactively around the clock.
Timelines depend on whether your building is already on or near our network. Where fiber is in place, activation can be quick; new builds include a site survey, design, construction, and end-to-end testing. We confirm a realistic timeline as part of your quote and handle professional installation for you.
We operate 5,000+ route miles of privately owned underground fiber across California and continue to expand. Share your address and bandwidth target and our engineers will confirm availability and recommend the right circuit.
