What is DIA (Fibre)-based Internet?

Dedicated Internet Access (DIA) over fibre gives your business a private, guaranteed internet connection. Unlike shared services like GPON or cable, DIA delivers a direct link from your building to the internet backbone—no sharing with neighbours, and no compromise on performance.

It’s the gold standard for businesses that depend on reliable connectivity for operations, communication, and growth.

How It Works for Businesses

With Dedicated Internet Access, fibre is installed directly to your location and configured for your exclusive use. You get a fixed bandwidth package—like 100 Mbps, 1 Gbps, or even 10 Gbps—that’s always available, regardless of network traffic in your area.

DIA typically includes a service-level agreement (SLA) guaranteeing uptime, latency, and support response times. It’s managed and monitored 24/7 by the provider.

Typical Speeds and Performance

Speeds are symmetrical and scalable—what you get downstream is what you get upstream. Many businesses start at 100 Mbps to 1 Gbps, with larger organizations going even higher.

Latency is extremely low, jitter is minimal, and packet loss is near zero. This level of performance is critical for cloud-based platforms, video meetings, VoIP systems, VPNs, and large-scale data transfer.

Pros and Cons

Why Businesses Choose Dedicated Internet Access:

  • Guaranteed speeds and performance, 24/7
  • Comes with enterprise-grade SLAs
  • Supports mission-critical applications with high reliability
  • Easily scalable as business needs grow

Things to Consider:

  • Higher monthly cost than shared fibre or cable
  • May require construction if fibre isn’t already in the building
  • Longer setup timelines depending on location

When It Makes Sense

Dedicated Internet Access (DIA) is ideal for businesses where internet downtime is not an option. That includes companies running call centres, data-heavy operations, e-commerce, or anything where speed and reliability directly impact revenue or productivity.

It’s also a smart move for growing organizations that want a scalable, future-proof solution from the start.
