What is Dedicated Internet Access (DIA)?

Dedicated Internet Access (DIA) is a private, high-speed connection between your premises and the internet. The connection is uncontended, meaning it’s not shared with other customers. Your provider runs a private leased line to your business’s local area network (LAN) or wide area network (WAN).

Typically, DIA is delivered using fibre optic cables and Ethernet, providing fixed symmetric upload and download speeds up to 10Gbps. Since any bandwidth you purchase is exclusively allocated for your use, your connection is unaffected by network congestion, and your actual internet speeds are guaranteed.

That’s why DIA is commonly used by businesses and organisations that need fast, reliable connectivity to run critical applications.
What is the difference between DIA and business broadband?

Dedicated Internet Access is a private, uncontended connection for a single customer. By contrast, business broadband provides a shared connection that distributes the bandwidth between multiple users in a local area.

While DIA offers a more consistent, reliable connection than broadband, it’s more expensive, so you’ll need to weigh the costs and benefits.

What are the benefits of DIA for businesses?

A dedicated internet connection offers several advantages over traditional business broadband. Here are some of the main benefits.
High speed

A dedicated line provides a consistent fixed bandwidth. Unlike broadband, DIA’s guaranteed upload/download bandwidth ensures a fast, low latency connection.
Reliability

The best DIA services have strict Service Level Agreements (SLAs), giving you confidence in availability and performance. In addition, you should expect your provider to be operating a resilient core network.
Scalability

Dedicated connections are usually highly scalable, allowing you to easily boost or cut bandwidth to meet your changing needs. A good DIA provider will allow you to increment bandwidth gradually as you grow.
Security

A key aspect of security is availability. As you don’t share bandwidth with other customers, you have more certainty over the availability of your internet access. In addition, you can order diverse circuits for important sites to protect your business from fibre breaks in the ‘last mile’ connectivity.

Who is DIA suitable for?

DIA is suitable for a range of businesses and organisations that rely on internet connectivity for critical operations, including:

    Medium to large enterprises: Larger businesses rely on DIA to support critical operations across dispersed sites, including data sharing, collaboration tools and other cloud-based services.
    Data-intensive industries: DIA can provide the bandwidth and security crucial for sectors processing high volumes of data, such as data centres, manufacturing, health care and financial services.
    Government agencies: DIA can ensure reliable internet connectivity for local and national governments to deliver essential services.
    Education and research: Schools, colleges and universities use DIA to communicate among students and staff and share data between institutions.
    E-commerce: DIA can provide reliable internet connectivity for online retailers to run their websites, manage customer accounts, and process orders.

If you have multiple, geographically dispersed sites in an enterprise wide area network (WAN), DIA can be a cost-effective way to provide local internet connectivity.

In short, DIA can work well for any organisation that needs reliable, high-performance connectivity for daily operations. However, DIA costs more than traditional business broadband, so it won’t suit every business.
